123 SARA-R5 series - System integration manual 1 System description 1.1 Overview The SARA-R5 series LTE Cat M1 / NB2 modules are ideal solutions for IoT, in the miniature SARA LGA form factor (26.0 x 16.0 mm, 96-pin). They allow an easy integration into compact designs and a seamless drop-in migration from other u-blox cellular module families. SARA-R5 series modules are form-factor compatible with u-blox LISA, LARA and TOBY cellular module families and are pin-to-pin compatible with u-blox SARA-N, SARA-G and SARA-U cellular module families. This facilitates migration from u-blox NB-IoT, GSM/GPRS, CDMA, UMTS/HSPA and other LTE modules, maximizes customer investments, simplifies logistics, and enables very short time-to-market. See Table 1 for a summary of the main features and interfaces.

Once a valid VCC supply is applied to the SARA-R500S and the SARA-R510M8S modules, this event triggers the switch on routine of the modules that subsequently enter the active mode. Instead, once a valid VCC supply is applied to the SARA-R510S modules, they remain switched off in power-off mode. Then the proper toggling of the PWR_ON input line is necessary to trigger the switch on routine of the modules that subsequently enter the active mode. SARA-R5 series modules are fully ready to operate when in active mode: the available communication interfaces are completely functional and the module can accept and respond to any AT command, entering connected mode upon LTE signal reception / transmission. The internal GNSS functionality can be concurrently enabled on the SARA-R510M8S modules by the dedicated +UGPS AT command, as well as the possible external GNSS functionality can be concurrently enabled using SARA-R500S or SARA-R510S modules by the dedicated +UGPS AT command. Then, the SARA-R5 series modules switch from active mode to the low power idle mode whenever possible, if the low power configuration is enabled by the dedicated +UPSV AT command. The low power idle mode can last for different time periods according to the specific +UPSV AT command setting, according to the specific +CEDRXS / +CEDRXRDP AT commands setting, and according to the concurrent activities executed by the module, as for example according to the concurrent GNSS activities. Then, after having enabled the low power configuration by the dedicated +UPSV AT command, according to the +CPSMS / +UCPSMS AT commands setting, and according to the concurrent activities executed by the module (for example according to the concurrent GNSS activities), whenever possible the SARA-R500S and SARA-R510M8S modules can enter the PSM deep-sleep mode and the SARA-R510S modules can enter the ultra-low power PSM deep-sleep mode. Once the modules enter the PSM deep-sleep mode (SARA-R500S and SARA-R510M8S modules) or the ultra-low power PSM deep-sleep mode (SARA-R510S modules), the available communication interfaces are not functional: a wake up event, consisting in proper toggling of the PWR_ON input line, the expiration of the Periodic Update Timer set by the LTE network, or the expiration of an RTC alarm, is necessary to trigger the wake up routine of the modules that subsequently enter back into the active mode. SARA-R5 series modules can be gracefully switched off by the dedicated +CPWROFF AT command, or by proper toggling of the PWR_ON input line. See the SARA-R5 series AT commands manual [2], +UPSV, +CEDRXS, +CEDRXRDP, +CPSMS,
+UCPSMS, +UGPS, +CALA, +CPWROFF AT commands, for the possible configurations and settings of different operating modes. UBX-19041356 - R03 Confidential System description Page 16 of 123 SARA-R5 series - System integration manual 1.5 Supply interfaces 1.5.1 Module supply input (VCC) The modules must be supplied via the three VCC pins that represent the module power supply input. Voltage must be stable, because during operation, the current drawn by the SARA-R5 series modules through the VCC pins may vary significantly, depending on the operating mode and state (as described in sections 1.5.1.2, 1.5.1.3, 1.5.1.4 and 1.5.1.5). It is important that the supply source is able to withstand the average current consumption occurring during Tx / Rx call at maximum RF power level (see the SARA-R5 series data sheet [1]). The 3 VCC pins of SARA-R5 series modules are internally connected each other to both the internal Power Amplifier and the internal baseband Power Management Unit. Figure 6 provides a simplified block diagram of SARA-R5 series modules internal VCC supply routing. Figure 6: Block diagram of SARA-R5 series modules internal VCC supply routing 1.5.1.1 VCC supply requirements Table 5 summarizes the requirements for the VCC modules supply. See section 2.2.1 for suggestions to correctly design a VCC supply circuit compliant with the requirements listed in Table 5. The supply circuit affects the RF compliance of the device integrating SARA-R5 series modules with applicable required certification schemes as well as antenna circuit design. Compliance is guaranteed if the requirements summarized in the Table 5 are fulfilled. Item Requirement Remark VCC nominal voltage Within VCC normal operating range:
3.3 V / 4.4 V VCC voltage during normal operation Within VCC extended operating range:
3.0 V / 4.5 V RF performance is guaranteed when VCC voltage is inside the normal operating range limits. RF performance may be affected when VCC voltage is outside the normal operating range limits, though the module is still fully functional until the VCC voltage is inside the extended operating range limits. VCC voltage must be above the extended operating range minimum limit to switch-on the module. The module may switch-off when the VCC voltage drops below the extended operating range minimum limit. Operation above VCC extended operating range is not recommended and may affect device reliability. UBX-19041356 - R03 Confidential System description Page 17 of 123 SARA-R5 series VCC 53 VCC 52 VCC 51 Power Management Unit Power Amplifier Transceiver Baseband Processor Memory SARA-R5 series - System integration manual Item VCC current Requirement Remark Support with adequate margin the highest averaged VCC current consumption value during Tx conditions specified in the SARA-R5 series data sheet [1]
VCC voltage ripple Noise in the supply pins must be minimized The maximum average current consumption can be greater than the specified value according to the actual antenna mismatching, temperature and supply voltage. Section 1.5.1.2 describes current consumption profiles in connected mode. High supply voltage ripple values during RF transmissions in connected mode directly affect the RF compliance with the applicable certification schemes. Table 5: Summary of VCC modules supply requirements 1.5.1.2 VCC current consumption in LTE connected mode During an LTE connection, the SARA-R5 series modules transmit and receive in half duplex mode. The current consumption depends on output RF power, which is always regulated by the network (the current base station) sending power control commands to the module. These power control commands are logically divided into a slot of 0.5 ms (time length of one Resource Block), thus the rate of power change can reach a maximum rate of 2 kHz. Figure 7 shows an example of SARA-R5 series modules current consumption profile versus time in connected mode: transmission is enabled for one sub-frame (1 ms) according to LTE Category M1 half-duplex connected mode. Detailed current consumption values can be found in the SARA-R5 series data sheet [1]. Figure 7: VCC current consumption profile versus time during LTE Cat M1 half-duplex connection 1.5.1.3 VCC consumption in deep-sleep mode
(low power mode and PSM enabled) The low power mode and the PSM configurations are by default disabled, but they can be enabled using the +UPSV and +CPSMS AT commands (see the SARA-R5 series AT commands manual [2]). When low power mode and PSM are enabled, whenever possible the modules automatically enter the PSM deep-sleep mode (SARA-R500S and SARA-R510M8S modules) or the ultra-low power PSM deep-sleep mode (SARA-R510S), reducing current consumption down to the lowest steady value: only the RTC runs with internal 32 kHz reference clock frequency.

SARA-R5 series - System integration manual 1.5.1.4 VCC current consumption in low power idle mode
(low power mode enabled) The low power mode configuration is by default disabled, but it can be enabled using the +UPSV AT command (see the SARA-R5 series AT commands manual [2]). When low power mode is enabled, the module automatically enters the low power idle mode whenever possible, but it must periodically monitor the paging channel of the current base station (paging block reception), in accordance to the 2G / LTE system requirements, even if connected mode is not enabled by the application. When the module monitors the paging channel, it wakes up to the active mode to enable the reception of the paging block. In between, the module switches to low power mode. This is known as discontinuous reception (DRX) or extended discontinuous reception (eDRX). 1.5.1.5 VCC current consumption in active mode
(low power mode and PSM disabled) The active mode is the state where the module is switched on and ready to communicate with an external device by means of the application interfaces (as the UART serial interface). The module processor core is active and the 26 MHz reference clock frequency is used. If low power mode configuration is disabled, as it is by default (see the SARA-R5 series AT commands manual [2], +UPSV AT commands for details), the module remains in active mode. Otherwise, if low power mode configuration is enabled, the module enters low power idle mode (and deep-sleep mode power saving mode, if enabled) whenever possible. Figure 8 shows a typical example of the module current consumption profile when the module is in active mode. Here, the module is registered with the network and, while active mode is maintained, the receiver is periodically activated to monitor the paging channel for paging block reception.

SARA-R5 series - System integration manual 1.5.2 Generic digital interfaces supply output (V_INT) The same voltage domain internally used as supply for the generic digital interfaces of SARA-R5 series modules is also available on the V_INT output pin, as illustrated in Figure 9. The internal regulator that generates the V_INT supply output is a switching (DC-DC) converter, which is directly supplied from the VCC main supply input of the module. The V_INT voltage regulator output of SARA-R5 series modules is disabled (i.e. 0 V) when the module is switched off, and it can be used to monitor the operating mode of the module as follows:
When the module is off, or in deep-sleep mode, the voltage level is low (i.e. 0 V) When the module is on, outside deep-sleep mode, the voltage level is high (i.e. 1.8 V) The current capability is specified in the SARA-R5 series data sheet [1]. The V_INT voltage domain can be used in place of an external discrete regulator as a reference voltage rail for external components.

Applying a voltage at the VCC module supply input within the operating range (see SARA-R5 series data sheet [1]). When the SARA-R510S modules are in the not-powered mode (i.e. switched off, with the VCC module supply not applied), the switch on routine can be triggered by:
Applying a voltage at the VCC module supply input within the operating range (see SARA-R5 series data sheet [1]), and then forcing a low level at the PWR_ON input pin (normally high due to internal pull-up) for a valid time period. When the SARA-R5 series modules are in the power-off mode (i.e. switched off, but with a valid voltage present at the VCC module supply input) or in deep-sleep mode, they can be switched on or they can be woken up as following:
Forcing a low level at the PWR_ON input pin (normally high due to internal pull-up) for a valid time period. As illustrated in Figure 10, the PWR_ON input pin is equipped with an internal pull-up resistor. Detailed electrical characteristics with voltages and timings are described in the SARA-R5 series data sheet [1].

The external power supply is applied to the VCC module pins, representing the start-up event. All the generic digital pins are tri-stated until the switch-on of their supply source (V_INT). The internal reset signal is held low: the baseband core and all digital pins are held in reset state. When the internal reset signal is released, any digital pin is set in the correct sequence from the reset state to the default operational configured state. The duration of this phase differs within generic digital interfaces and USB interface due to host / device enumeration timings. If enabled, a greeting message is sent on the RXD pin (for more details, see SARA-R5 series AT commands manual [2]) The module is fully ready to operate after all interfaces are configured. Figure 11: SARA-R500S / SARA-R510M8S switch-on sequence description from not-powered mode Figure 12 shows the SARA-R510S modules switch-on sequence from the not-powered mode:

The external power supply is still applied to the VCC module pins, with the module being previously switched off (by means of the +CPWROFF AT command or by proper PWR_ON pin toggling), or with the module being previously entered deep-sleep mode. The PWR_ON pin is held low for a valid time, representing the start-up event. All the generic digital pins are tri-stated until the switch-on of their supply source (V_INT). The internal reset signal is held low: the baseband core and all digital pins are held in reset state. When the internal reset signal is released, any digital pin is set in the correct sequence from the reset state to the default operational configured state. The duration of this phase differs within generic digital interfaces and USB interface due to host / device enumeration timings. If enabled, a greeting message is sent on the RXD pin (for more details, see SARA-R5 series AT commands manual [2]) The module is fully ready to operate after all interfaces are configured. Figure 13: SARA-R5 series switch-on / wake-up sequence description from power-off / deep-sleep mode 1.6.1.4 General considerations for the switch-on procedure If the greeting text is not used by the external application to detect that the module is ready to reply to AT commands, then the only way of checking it is polling: the external application can start sending AT after that the CTS line is set to the ON state (in case UART is used as AT interface with HW flow control enabled as default), but any AT command sent before the time when the module is ready to reply may be not buffered and may be lost. The Internal Reset signal is not available on a module pin, but it is highly recommended to monitor:
o the V_INT pin, to sense the start of the SARA-R5 series module switch-on sequence o the GPIO pin configured to provide the module status indication or module operating mode indication (see SARA-R5 series AT commands manual [2], +UGPIOC), to sense when the module is ready to operate Before the switch-on of the generic digital interface supply (V_INT) of the module, no voltage driven by an external application should be applied to any generic digital interface of the module. The duration of the SARA-R5 series modules switch-on routine can vary depending on the application / network settings and the concurrent module activities.

+CPWROFF AT command (see SARA-R5 series AT commands manual [2]). Forcing a low pulse on the PWR_ON pin (normally high due to internal pull-up) for a valid time period (see the SARA-R5 series data sheet [1]). A fast emergency shutdown procedure of the modules, without storage of the current parameter settings in the modules non-volatile memory and without proper network detach, can be triggered by:
Toggling the GPIO input pin configured with fast emergency shutdown function (see section 1.11) An abrupt under-voltage shutdown occurs on SARA-R5 series modules when the VCC supply is removed. If this occurs, it is not possible to perform the storing of the current parameter settings in the modules non-volatile memory or to perform the proper network detach. It is highly recommended to avoid an abrupt removal of the VCC supply during SARA-R5 series modules normal operations. 1.6.2.2 Switch-off sequence by +CPWROFF AT command Figure 14 describes the switch-off sequence of the modules started by the +CPWROFF AT command, allowing storage of parameter settings in the non-volatile memory and a clean network detach:
When the +CPWROFF AT command is sent the module starts the switch-off routine. Then the module replies OK on the AT interface: the switch-off routine is in progress. At the end of the switch-off routine, all the digital pins are tri-stated and all the internal voltage regulators are turned off, including the generic digital interfaces supply (V_INT). Then, the module remains in switch-off mode as long as a switch-on event does not occur
(e.g. applying a low level to PWR_ON), or enters not-powered mode if the VCC supply is removed. Figure 14: SARA-R5 series modules switch-off sequence by means of +CPWROFF AT command The Internal Reset signal is not available on a module pin, but it is highly recommended to monitor the V_INT pin to sense the end of the switch-off sequence.

Forcing a low pulse on the PWR_ON pin (normally high due to internal pull-up) for a valid time period (higher than the period for the graceful switch-off, see the SARA-R5 series data sheet [1]). It is highly recommended to avoid an abrupt emergency hardware reset during module normal operation: this should be used only if software reset (via AT commands or via RESET_N pin) or graceful switch-off (via AT commands or via PWR_ON pin) fails. As described in Figure 16, the RESET_N input pin is directly connected to the processor core, with an integrated active pull-up, in order to perform an abrupt software reset when asserted, excluding the power management unit. Detailed electrical characteristics with voltages and timings are described in the SARA-R5 series data sheet [1].

The ANT pin represents the RF input/output for transmission and reception of LTE RF signals. The ANT pin has a nominal characteristic impedance of 50 and must be connected to the Tx / Rx cellular antenna through a 50 transmission line to allow proper RF transmission and reception. 1.7.1.1 Cellular antenna RF interface requirements Table 6 summarizes the requirements for the cellular antenna RF interface. See section 2.4.2 for suggestions to correctly design antennas circuits compliant with these requirements. The antenna circuits affect the RF compliance of the device integrating SARA-R5 series modules with applicable required certification schemes (for more details see section 4). Compliance is guaranteed if the antenna RF interface requirements summarized in Table 6 are fulfilled. Item Requirements Remarks Impedance 50 nominal characteristic impedance The impedance of the antenna RF connection must match the 50 impedance of the ANT port.

The return loss or the S11, as the VSWR, refers to the amount of reflected power, measuring how well the antenna RF connection matches the 50 characteristic impedance of the ANT port. The impedance of the antenna termination must match as much as possible the 50 nominal impedance of the ANT port over the operating frequency range, reducing as much as possible the amount of reflected power. The radiation efficiency is the ratio of the radiated power to the power delivered to antenna input: the efficiency is a measure of how well an antenna receives or transmits. The radiation efficiency of the antenna connected to the ANT port needs to be enough high over the operating frequency range to comply with the Over-The-Air (OTA) radiated performance requirements, as Total Radiated Power (TRP) and the Total Isotropic Sensitivity (TIS), specified by applicable related certification schemes. The power gain of an antenna is the radiation efficiency multiplied by the directivity: the gain describes how much power is transmitted in the direction of peak radiation to that of an isotropic source. The maximum gain of the antenna connected to ANT port must not exceed the herein stated value to comply with regulatory agencies radiation exposure limits. The antenna connected to the ANT port must support with adequate margin the maximum power transmitted by the modules.

SARA-R510M8S modules provide an RF interface for connecting the external GNSS antenna. The ANT_GNSS pin represents the RF input reception of GNSS RF signals. The ANT_GNSS pin has a nominal characteristic impedance of 50 and must be connected to the Rx GNSS antenna through a 50 transmission line to allow proper RF reception. As shown in Figure 4, the GNSS RF interface is designed with an internal DC block, and is suitable for both active and/or passive GNSS antennas due to the built-in SAW filter followed by an additional LNA in front of the integrated high performing u-blox M8 concurrent position engine. 1.7.2.1 GNSS antenna RF interface requirements Table 7 summarizes the requirements for the GNSS antenna RF interface. See section 2.4.3 for suggestions to correctly design antennas circuits compliant with these requirements.

The required frequency range of the antenna connected to ANT_GNSS port depends on the selected GNSS constellations. The return loss or the S11, as the VSWR, refers to the amount of reflected power, measuring how well the antenna RF connection matches the 50 characteristic impedance of the ANT_GNSS port. The impedance of the antenna termination must match as much as possible the 50 nominal impedance of the ANT_GNSS port over the operating frequency range, reducing as much as possible the amount of reflected power. The antenna gain defines how efficient the antenna is at receiving the signal. It is important providing good antenna visibility to the sky, using antennas with good radiation pattern in the sky direction, according to related antenna placement. Since GNSS signals are very weak, any amount of noise degrades all the sensitivity figures of the receiver: active antennas with LNA with a low noise figure are recommended. GNSS signals are circularly-polarized. The purity of the antenna circular polarization is stated in terms of axial ratio (AR), defined as the ratio of the vertical electric field to the horizontal electric field on polarization ellipse at zenith. Gain
(active antenna) 17 dB minimum, 30 dB maximum The antenna gain defines how efficient the antenna is at receiving the signal. It is directly related to the overall C/No. UBX-19041356 - R03 Confidential System description Page 28 of 123 SARA-R5 series - System integration manual 1.7.3 Cellular antenna detection interface (ANT_DET) The antenna detection is based on ADC measurement. The ANT_DET pin is an analog to digital converter (ADC) provided to sense the antenna presence. The antenna detection function provided by ANT_DET pin is an optional feature that can be implemented if the application requires it. The antenna detection is forced by the +UANTR AT command. See the SARA-R5 series AT commands manual [2] for more details on this feature. The ANT_DET pin generates a DC current (for detailed characteristics see the SARA-R5 series data sheet [1]) and measures the resulting DC voltage, thus determining the resistance from the antenna connector provided on the application board to GND. So, the requirements to achieve antenna detection functionality are the following:
an RF antenna assembly with a built-in resistor (diagnostic circuit) must be used an antenna detection circuit must be implemented on the application board See section 2.4.4 for antenna detection circuit on application board and diagnostic circuit on antenna assembly design-in guidelines. 1.7.4 Cellular and GNSS coexistence Desensitization or receiver blocking is a form of electromagnetic interference where a radio receiver is unable to detect a weak signal that it might otherwise be able to receive when there is no interference (see Figure 17). Good blocking performance is particularly important in the scenarios where a number of radios of various forms are used in close proximity to each other. This is the case with SARA-R510M8S modules integrating both an LTE radio and a GNSS receiver. Figure 17: Interference signals due to LTE transmission. Low channels in LTE B3, B4 and B66 (1710 MHz) are close to GNSS frequencies (1561 to 1605 MHz). Harmonics due to transmission in LTE B13 and B18 may also fall into the GNSS bands.

SARA-R5 series - System integration manual Jamming signals come from in-band and out-band frequency sources. In-band jamming is caused by signals with frequencies within or close to the GNSS constellation frequency used, while out-band jamming is caused by very strong signals with frequencies different from the GNSS carrier, that is picked up at the input of the GNSS receiver and that can saturate the receiver front-end. if not properly taken into consideration those signals cause a reduction in the carrier-to-noise power density ratio (C/No) of the GNSS satellites. In-band interference signals are typically caused by harmonics from displays, switching converters, micro-controllers and bus systems. Moreover, considering for example the LTE Band 13 high channel transmission frequency (787 MHz) and the GPS operating band (1575.42 MHz 1.023 MHz), the second harmonic of the cellular signal is exactly within the GPS operating band. Therefore, depending on the board layout and the transmit power, the highest channel of LTE Band 13 is the channel that has the greatest impact on the C/No reduction. Countermeasures against in-band interference include:
maintaining a good grounding concept in the design ensuring proper shielding of the different RF paths ensuring proper impedance matching of RF traces placing the GNSS antenna away from noise sources add a notch filter along the GNSS RF path, in front of SAW filter, at the frequency of the jammer
(as for example, a notch filter at ~787 MHz improves the immunity to LTE Band 13 high channel) Out-band interference is caused by signal frequencies that are different from the GNSS, the main sources being cellular, Wi-Fi, bluetooth transmitters, etc. For example, the lowest channels in LTE Band 3, 4 and 66 can compromise the good reception of the GLONASS satellites. Again, the effect can be explained by comparing the LTE frequencies (low channels transmission frequency is 1710 MHz) with the GLONASS operating band (1602 MHz 8 MHz). In this case the LTE signal is outside the useful GNSS band, but, provided that the power received by the GNSS subsystem at 1710 MHz is high enough, blocking effects may appear reducing once again the C/No. Countermeasures against out-band interference include:
maintaining a good grounding concept in the design keeping the GNSS and cellular antennas more than the quarter-wavelength (of the minimum Tx frequency) away from each other. If for layout or size reasons the aforementioned requirement cannot be met, then the antennas should be placed orthogonally to each other and/or on different side of the PCB. ensuring at least 15 20 dB isolation between antennas in the GNSS band adding a GNSS pass-band SAW filter along the GNSS RF line, providing very large attenuation in the cellular frequency bands (as for example Murata SAFFB1G56AC0F0A, or SAFFB1G56AC0F7F). It has to be noted that, as shown in Figure 3, a SAW filter and an LNA are already integrated in the GNSS RF path of the SARA-R510M8S: the addition of an external filter along the GNSS RF line has to be considered only if the conditions above cannot be met. adding a GNSS stop-band SAW filter along the cellular RF line, providing very low attenuation in the cellular frequency bands (as for example the Qualcomm B8636, or B8666). It has to be noted that the addition of an external filter along the cellular RF line has to be carefully evaluated as further countermeasure only if the conditions above cannot be met in different way, considering that an external filter may affect the cellular TRP and/or TIS RF performance figures. As far as Tx power is concerned, SARA-R5 series modules maximum output power during LTE transmission is 23 dBm. High-power transmission occurs very infrequently: typical output power values are in the range of -3 to 0 dBm (see Figure 1 in the GSMA official document TS.09 [10]). Therefore, depending on the application, careful PCB layout and antenna placement should be sufficient to ensure accurate GNSS reception.

Both 1.8 V and 3 V SIM types are supported. Activation and deactivation with automatic voltage switch from 1.8 V to 3 V are implemented, according to ISO-IEC 7816-3 specifications. The VSIM supply output provides internal short circuit protection to limit start-up current and protects the SIM to short circuits. 1.8.2 SIM card detection interface (GPIO5) The GPIO5 pin is configured as an external interrupt to detect the SIM card mechanical / physical presence. The pin is configured as input with an internal active pull-down enabled, and it can sense SIM card presence only if cleanly connected to the mechanical switch of a SIM card holder as described in section 2.5:
Low logic level at GPIO5 input pin is recognized as SIM card not present High logic level at GPIO5 input pin is recognized as SIM card present The SIM card detection function provided by GPIO5 pin is an optional feature that can be implemented or not according to the application requirements. For more details, see the SARA-R5 series AT commands manual [2], +UGPIOC, +CIND and +CMER AT commands. 1.9 Data communication interfaces SARA-R5 series modules provide the following serial communication interfaces:

Serial port with RS-232 functionality conforming to the ITU-T V.24 recommendation [5], with CMOS compatible levels (0 V for low data bit or ON state, and 1.8 V for high data bit or OFF state) Hardware flow control (default value) or none flow control are supported UART power saving indication available on the hardware flow control output, if hardware flow control is enabled: the line is driven to the OFF state when the module is not prepared to accept data by the UART interface One-shot autobauding is supported and it is enabled by default: automatic baud rate detection is performed only once, at module start up. After the detection, the module works at the fixed baud rate (the detected one) and the baud rate can be changed via AT command The default frame format is 8N1 (8 data bits, no parity, 1 stop bit) SARA-R5 series modules are designed to operate as cellular modems, i.e. as the data circuit-terminating equipment (DCE) according to the ITU-T V.24 recommendation [5]. A host application processor connected to the module UART interface represents the data terminal equipment (DTE). UART signal names of the cellular modules conform to the ITU-T V.24 recommendation [5]:
e.g. TXD line represents data transmitted by the DTE (host processor output) and received by the DCE (module input). SARA-R5 series modules UART interface is by default configured for AT commands: the module waits for AT command instructions and interprets all the characters received as commands to execute. All the functionalities supported by SARA-R5 series modules can be in general set and configured by AT commands:
AT commands according to 3GPP TS 27.007 [6], 3GPP TS 27.005 [7], 3GPP TS 27.010 [8]
u-blox AT commands (see the SARA-R5 series AT commands manual [2]) The UART interfaces settings can be suitably configured by AT commands (for more details, see the SARA-R5 series AT commands manual [2]). Figure 18 describes the 8N1 frame format.

(Always 1) SARA-R5 series - System integration manual 1.9.1.2 UART signals behavior At the end of the module boot sequence (see Figure 11, Figure 12, Figure 13), the module is by default in active mode, and the UART interface is initialized and enabled as AT commands interface. The configuration and behavior of the UART signals after the boot sequence are described below:
The module data output lines (RXD only if USIO variant 0 or 1 is set; RXD and DCD if USIO variant 2, 3 or 4 is set) are set by default to the OFF state (high level) at UART initialization. The module holds these lines in the OFF state until the module transmits some data. The module data input lines (TXD only if USIO variant 0 or 1 is set; TXD and DTR if USIO variant 2, 3 or 4 is set) are assumed to be controlled by the external host once UART is initialized. The data input lines have an internal active pull-up enabled. 1.9.1.3 UART multiplexer protocol SARA-R5 series modules include multiplexer functionality as per 3GPP TS 27.010 [8], on the UART physical link. This is a data link protocol which uses HDLC-like framing and operates between the module (DCE) and the application processor (DTE) and allows a number of simultaneous sessions over the used physical link (UART). When USIO variant 0 or 1 is set, the following virtual channels are defined:
When USIO variant 2 is set, AT commands and data communication are available on second auxiliary UART, and the following virtual channels are defined on main primary UART:
When USIO variant 3 is set, diagnostic trace log is available on second auxiliary UART, and the following virtual channels are defined on main primary UART:
Channel 0: control channel Channel 1 3: AT commands / data communication Channel 4: GNSS tunneling Channel 0: control channel Channel 1 2: AT commands / data communication Channel 3: GNSS tunneling Channel 0: control channel Channel 1 3: AT commands / data communication Channel 4: GNSS tunneling Channel 0: control channel Channel 1 3: AT commands / data communication 1.9.2 USB interface When USIO variant 4 is set, GNSS tunneling is available on second auxiliary UART, and the following virtual channels are defined on main primary UART:
SARA-R5 series modules include a high-speed USB 2.0 compliant interface with a maximum 480 Mbit/s data rate according to the Universal Serial Bus Revision 2.0 specification [4]. The module itself acts as a USB device and can be connected to any USB host equipped with compatible drivers. The USB interface is available for diagnostic purpose only. The USB_D+ / USB_D- lines carry the USB data / signaling, while the VUSB_DET input pin represents the input to enable the USB interface by applying an external valid USB VBUS voltage (5 V typical). UBX-19041356 - R03 Confidential System description Page 34 of 123 SARA-R5 series - System integration manual 1.9.3 SPI interfaces The SPI interface are not supported by the 00 product version of SARA-R5 series modules, except for diagnostic purpose. SARA-R5 series modules include 1.8 V Serial Peripheral Interfaces available for communications with external SPI slave devices, or for diagnostic purpose with the module acting as SPI master. 1.9.4 SDIO interface The SDIO interface is not supported by the 00 product version of SARA-R5 series modules. SARA-R5 series modules include a 1.8 V 4-bit Secure Digital Input Output interface over the SDIO_D0, SDIO_D1, SDIO_D2, SDIO_D3, SDIO_CLK and SDIO_CMD pins, with the module acting as an SDIO host, available for communications with compatible external SDIO devices, and for diagnostic purpose. 1.9.5 DDC (I2C) interface Communication with an external GNSS receiver is not supported by SARA-R510M8S modules. SARA-R5 series modules include a 1.8 V I2C-bus compatible DDC interface over the SDA and SCL pins, available to communicate with an external u-blox GNSS receiver and with external I2C devices as for example an audio codec: the SARA-R5 series module acts as an I2C master that can communicate with I2C slaves in accordance with the I2C bus specifications [9]. The same 1.8 V I2C-bus compatible DDC interface is internally connected to the u-blox M8 GNSS chipset integrated in SARA-R510M8S modules, as illustrated in Figure 4. The SDA and SCL pins have internal active pull-up, so there is no need of additional pull-up resistors on the external application board. 1.10 Audio Audio is not supported by 00 product version of SARA-R5 series modules. SARA-R5 series modules include a 1.8 V I2S digital audio interface over the I2S_TXD, I2S_RXD, I2S_CLK and I2S_WA pins for transferring digital audio data with an external compatible digital audio device.

UBX-19041356 - R03 Confidential System description Page 36 of 123 SARA-R5 series - System integration manual 2 Design-in 2.1 Overview For an optimal integration of the SARA-R5 series modules in the final application board, follow the design guidelines stated in this section. Every application circuit must be suitably designed to guarantee the correct functionality of the relative interface, but a number of points require particular attention during the design of the application device. The following list provides a rank of importance in the application design, starting from the highest relevance:
1. Module antennas connection: ANT, ANT_GNSS 6 and ANT_DET pins. Antenna circuit directly affects the RF compliance of the device integrating a SARA-R5 series module with applicable certification schemes. Follow the suggestions provided in the relative section 2.4 for schematic and layout design. 2. Module supply: VCC and GND pins. The supply circuit affects the RF compliance of the device integrating a SARA-R5 series module with the applicable required certification schemes as well as the antenna circuits design. Very carefully follow the suggestions provided in the relative section 2.2.1 for schematic and layout design. 3. SIM interface: VSIM, SIM_CLK, SIM_IO, SIM_RST pins. Accurate design is required to guarantee SIM card functionality reducing the risk of RF coupling. Carefully follow the suggestions provided in relative section 2.5 for schematic and layout design. 4. System functions: PWR_ON and RESET_N pins. Accurate design is required to guarantee that the voltage level is well defined during operation. Carefully follow the suggestions provided in relative section 2.3 for schematic and layout design. 5. Other digital interfaces: UART, USB, SPI, SDIO, I2C, I2S and GPIOs. Accurate design is required to guarantee correct functionality and reduce the risk of digital data frequency harmonics coupling. Follow the suggestions provided in sections 2.6, 2.7 and 2.8 for schematic and layout design. 6. Other supplies: V_INT generic digital interfaces supply. Accurate design is required to guarantee correct functionality. Follow the suggestions provided in the corresponding section 2.2.2 for schematic and layout design. It is recommended to follow the specific design guidelines provided by each manufacturer of any external part selected for the application board integrating the u-blox cellular modules. 6 Not supported by SARA-R500S and SARA-R510S modules UBX-19041356 - R03 Confidential Design-in Page 37 of 123 SARA-R5 series - System integration manual 2.2 Supply interfaces 2.2.1 Module supply (VCC) 2.2.1.1 General guidelines for VCC supply circuit selection and design All the available VCC pins have to be connected to the external supply minimizing the power loss due to series resistance. GND pins are internally connected. Application design shall connect all the available pads to solid ground on the application board, since a good (low impedance) connection to external ground can minimize power loss and improve RF and thermal performance. SARA-R5 series modules must be sourced through the VCC pins with a suitable DC power supply that should comply with the module VCC requirements summarized in Table 5. The appropriate DC power supply can be selected according to the application requirements (see Figure 19) between the different possible supply sources types, which most common ones are the following:
Switching regulator Low Drop-Out (LDO) linear regulator Rechargeable Lithium-ion (Li-Ion) or Lithium-ion polymer (Li-Pol) battery Primary (disposable) battery Figure 19: VCC supply concept selection The switching step-down regulator is the typical choice when primary supply source has a nominal voltage much higher (e.g. greater than 5 V) than the operating supply voltage of SARA-R5 series. The use of switching step-down provides the best power efficiency for the overall application and minimizes current drawn from the main supply source. See section 2.2.1.2 for design-in. The use of an LDO linear regulator becomes convenient for a primary supply with a relatively low voltage (e.g. less or equal than 5 V). In this case, the typical 90% efficiency of the switching regulator diminishes the benefit of voltage step-down and no true advantage is gained in input current savings. On the opposite side, linear regulators are not recommended for high voltage step-down as they dissipate a considerable amount of energy in thermal power. See section 2.2.1.3 for design-in. If SARA-R5 series modules are deployed in a mobile unit where no permanent primary supply source is available, then a battery will be required to provide VCC. A standard 3-cell Li-Ion or Li-Pol battery pack directly connected to VCC is the usual choice for battery-powered devices. During charging, batteries with Ni-MH chemistry typically reach a maximum voltage that is above the maximum rating for VCC, and should therefore be avoided. See sections 2.2.1.4, 2.2.1.5, 2.2.1.6 and 2.2.1.7 for specific design-in. UBX-19041356 - R03 Confidential Design-in Page 38 of 123 Main supply available?
No, portable device Battery Li-Ion 3.7 V Yes, always available Main supply voltage > 5V?
No, less than 5 V Yes, greater than 5 V Switching step-down Linear LDO regulator regulator SARA-R5 series - System integration manual Keep in mind that the use of rechargeable batteries requires the implementation of a suitable charger circuit, which is not included in the modules. The charger circuit needs to be designed to prevent over-voltage on VCC pins, and it should be selected according to the application requirements. A DC-DC switching charger is the typical choice when the charging source has a high nominal voltage
(e.g. ~12 V), whereas a linear charger is the typical choice when the charging source has a relatively low nominal voltage (~5 V). If both a permanent primary supply / charging source (e.g. ~12 V) and a rechargeable back-up battery (e.g. 3.7 V Li-Pol) are available at the same time as possible supply source, then a suitable charger / regulator with integrated power path management function can be selected to supply the module while simultaneously and independently charging the battery. See sections 2.2.1.6 and 2.2.1.7 for specific design-in. An appropriate primary (not rechargeable) battery can be selected taking into account the maximum current specified in the SARA-R5 series data sheet [1] during connected mode, considering that primary cells might have weak power capability. See section 2.2.1.5 for specific design-in. The usage of more than one DC supply at the same time should be carefully evaluated: depending on the supply source characteristics, different DC supply systems can result as mutually exclusive. The selected regulator or battery must be able to support with adequate margin the highest averaged current consumption value specified in the SARA-R5 series data sheet [1]. The following sections highlight some design aspects for each of the supplies listed above providing application circuit design-in compliant with the module VCC requirements summarized in Table 5. 2.2.1.2 Guidelines for VCC supply circuit design using a switching regulator The use of a switching regulator is suggested when the difference from the available supply rail source to the VCC value is high, since switching regulators provide good efficiency transforming a 12 V or greater voltage supply to the typical 3.8 V value of the VCC supply. The characteristics of the switching regulator connected to VCC pins should meet the following prerequisites to comply with the module VCC requirements summarized in Table 5:
Power capability: the switching regulator with its output circuit must be capable of providing a voltage value to the VCC pins within the specified operating range and must be capable of delivering to VCC pins the maximum current consumption occurring during transmissions at the maximum power, as specified in the SARA-R5 series data sheet [1]. Low output ripple: the switching regulator together with its output circuit must be capable of providing a clean (low noise) VCC voltage profile. PWM mode operation: it is preferable to select regulators with Pulse Width Modulation (PWM) mode. While in connected mode, the Pulse Frequency Modulation (PFM) mode and PFM/PWM modes transitions must be avoided to reduce noise on VCC voltage profile. Switching regulators can be used that are able to switch between low ripple PWM mode and high ripple PFM mode, provided that the mode transition occurs when the module changes status from the active mode to connected mode. It is permissible to use a regulator that switches from the PWM mode to the burst or PFM mode at an appropriate current threshold. Figure 20 and the components listed in Table 9 show an example of a power supply circuit for SARA-
R5 series modules. In this example, the module VCC is supplied by a step-down switching regulator capable of delivering the maximum peak / pulse current specified for the LTE use-case, with low output ripple and with fixed switching frequency in PWM mode operation greater than 1 MHz.

The characteristics of the Low Drop-Out (LDO) linear regulator connected to VCC pins should meet the following prerequisites to comply with the module VCC requirements summarized in Table 5:
Power capabilities: the LDO linear regulator with its output circuit must be capable of providing a voltage value to the VCC pins within the specified operating range and must be capable of delivering to VCC pins the maximum current consumption occurring during a transmission at the maximum Tx power, as specified in the SARA-R5 series data sheet [1]. Power dissipation: the power handling capability of the LDO linear regulator must be checked to limit its junction temperature to the rated range (i.e. check the voltage drop from the maximum input voltage to the minimum output voltage to evaluate the power dissipation of the regulator).

It is recommended to configure the LDO linear regulator to generate a voltage supply value slightly below the maximum limit of the module VCC normal operating range (e.g. ~4.1 V for the VCC, as in the circuits described in Figure 21 and Table 10). This reduces the power on the linear regulator and improves the thermal design of the circuit.

Maximum pulse and DC discharge current: the rechargeable Li-Ion battery with its related output circuit connected to the VCC pins must be capable of delivering the maximum current occurring during a transmission at maximum Tx power, as specified in SARA-R5 series data sheet [1]. The maximum discharge current is not always reported in the data sheets of batteries, but the maximum DC discharge current is typically almost equal to the battery capacity in Amp-hours divided by 1 hour. DC series resistance: the rechargeable Li-Ion battery with its output circuit must be capable of avoiding a VCC voltage drop below the operating range summarized in Table 5 during transmission.

Maximum pulse and DC discharge current: the non-rechargeable battery with its related output circuit connected to the VCC pins must be capable of delivering the maximum current consumption occurring during a transmission at maximum Tx power, as specified in SARA-R5 series data sheet [1]. The maximum discharge current is not always reported in the data sheets of batteries, but the maximum DC discharge current is typically almost equal to the battery capacity in Amp-hours divided by 1 hour. DC series resistance: the non-rechargeable battery with its output circuit must be capable of avoiding a VCC voltage drop below the operating range summarized in Table 5 during transmission. 2.2.1.6 Guidelines for external battery charging circuit SARA-R5 series modules do not have an on-board charging circuit. Figure 22 provides an example of a battery charger design, suitable for applications that are Li-Ion (or Li-Pol) battery powered. In the application circuit, a rechargeable Li-Ion (or Li-Pol) battery cell, that features the correct pulse and DC discharge current capabilities and the appropriate DC series resistance, is directly connected to the VCC supply input of the module. Battery charging is completely managed by the battery charger IC, which from a USB power source (5.0 V typ.), linearly charges the battery in three phases:
Pre-charge constant current (active when the battery is deeply discharged): the battery is Fast-charge constant current: the battery is charged with the maximum current, configured by charged with a low current. the value of an external resistor. Constant voltage: when the battery voltage reaches the regulated output voltage, the battery charger IC starts to reduce the current until the charge termination is done. The charging process ends when the charging current reaches the value configured by an external resistor or when the charging timer reaches the factory set value. Using a battery pack with an internal NTC resistor, the battery charger IC can monitor the battery temperature to protect the battery from operating under unsafe thermal conditions. The battery charger IC, as linear charger, is more suitable for applications where the charging source has a relatively low nominal voltage (~5 V), so that a switching charger is suggested for applications where the charging source has a relatively high nominal voltage (e.g. ~12 V, see section 2.2.1.7 for the specific design-in).

C3 C4 C5 C6 R1 U1 2.2.1.7 Guidelines for external charging and power path management circuit Application devices where both a permanent primary supply / charging source (e.g. ~12 V) and a rechargeable back-up battery (e.g. 3.7 V Li-Pol) are available at the same time as a possible supply source, should implement a suitable charger / regulator with integrated power path management function to supply the module and the whole device while simultaneously and independently charging the battery. Figure 23 reports a simplified block diagram circuit showing the working principle of a charger /
regulator with integrated power path management function. This component allows the system to be powered by a permanent primary supply source (e.g. ~12 V) using the integrated regulator, which simultaneously and independently recharges the battery (e.g. 3.7 V Li-Pol) that represents the back-up supply source of the system. The power path management feature permits the battery to supplement the system current requirements when the primary supply source is not available or cannot deliver the peak system currents. A power management IC should meet the following prerequisites to comply with the module VCC requirements summarized in Table 5:
High efficiency internal step down converter, with characteristics as indicated in section 2.2.1.2 Low internal resistance in the active path Vout Vbat, typically lower than 50 m High efficiency switch mode charger with separate power path control Figure 23: Charger / regulator with integrated power path management circuit block diagram UBX-19041356 - R03 Confidential Design-in Page 43 of 123 Power path management IC System 12 V primary source Vin DC/DC converter and battery FET control logic Charge controller GND Vout Vbat GND Li-Ion/Li-Pol battery pack SARA-R5 series - System integration manual Figure 24 and the parts listed in Table 12 provide an application circuit example where the MPS MP2617H switching charger / regulator with integrated power path management function provides the supply to the cellular module. At the same time it also concurrently and autonomously charges a suitable Li-Ion (or Li-Pol) battery with the correct pulse and DC discharge current capabilities and the appropriate DC series resistance according to the rechargeable battery recommendations described in section 2.2.1.4. The MP2617H IC constantly monitors the battery voltage and selects whether to use the external main primary supply / charging source or the battery as supply source for the module, and starts a charging phase accordingly. The MP2617H IC normally provides a supply voltage to the module regulated from the external main primary source allowing immediate system operation even under missing or deeply discharged battery: the integrated switching step-down regulator is capable to provide up to 3 A output current with low output ripple and fixed 1.6 MHz switching frequency in PWM mode operation. The module load is satisfied in priority, then the integrated switching charger will take the remaining current to charge the battery. Additionally, the power path control allows an internal connection from battery to the module with a low series internal ON resistance (40 m typical), in order to supplement additional power to the module when the current demand increases over the external main primary source or when this external source is removed. Battery charging is managed in three phases:
Pre-charge constant current (active when the battery is deeply discharged): the battery is charged with a low current, set to 10% of the fast-charge current Fast-charge constant current: the battery is charged with the maximum current, configured by the value of an external resistor to a value suitable for the application Constant voltage: when the battery voltage reaches the regulated output voltage (4.2 V), the current is progressively reduced until the charge termination is done. The charging process ends when the charging current reaches the 10% of the fast-charge current or when the charging timer reaches the value configured by an external capacitor Using a battery pack with an internal NTC resistor, the MP2617H can monitor the battery temperature to protect the battery from operating under unsafe thermal conditions. Several parameters as the charging current, the charging timings, the input current limit, the input voltage limit, the system output voltage can be easily set according to the specific application requirements, as the actual electrical characteristics of the battery and the external supply / charging source: suitable resistors or capacitors must be accordingly connected to the related pins of the IC.

The application processor can disconnect the VCC supply source from the module and zero out the modules current. The VCC supply source can be removed using an appropriate low-leakage load switch or p-channel MOSFET controlled by the application processor as shown in Figure 25, given that the external switch has provided:
Very low leakage current (for example, less than 1 A), to minimize the current consumption Very low RDS(ON) series resistance (for example, less than 50 m), to minimize voltage drops Adequate maximum drain current (see the SARA-R5 series data sheet [1] for module current consumption figures) Figure 25: Example of application circuit for VCC supply removal Reference Description Part number - Manufacturer 10 F capacitor ceramic X5R 0603 20% 6.3 V GRM188R60J106ME47 - Murata 10 nF capacitor ceramic X7R 0402 10% 16 V GRT155R71C103KE01 - Murata 100 nF capacitor ceramic X7R 0402 10% 16 V GCM155R71C104KA55 - Murata 68 pF capacitor ceramic C0G 0402 5% 50 V GRM1555C1H680JA16 - Murata 15 pF capacitor ceramic C0G 0402 5% 25 V GJM1555C1H150JB01 - Murata R1, R3 47 k resistor 0402 5% 0.1 W 10 k resistor 0402 5% 0.1 W NPN BJT transistor Generic manufacturer Generic manufacturer BC847 - Infineon Ultra-low resistance load switch TPS22967 - Texas Instruments Table 13: Components for VCC supply removal application circuit It is highly recommended to avoid an abrupt removal of the VCC supply during SARA-R5 series normal operations: the VCC supply can be removed only after V_INT goes low, indicating that the module has entered deep-sleep power saving mode or power-off mode. See the section 2.2.1.9, and in particular Figure 26 / Table 14, for the parts recommended to be provided if the application device integrates an internal antenna.

The series resistance of the supply lines
(connected to the modules VCC and GND pins) on the application board and battery pack should also be considered and minimized: cabling and routing must be as short as possible to minimize losses. Three pins are allocated to VCC supply connection. Several pins are designated for GND connection. It is recommended to correctly connect all of them to supply the module minimizing series resistance. To reduce voltage ripple and noise, improving RF performance especially if the application device integrates an internal antenna, place the following bypass capacitors near the VCC pins:
68 pF capacitor with self-resonant frequency in the 700/800/900 MHz range (e.g. Murata GRM1555C1H680J), to filter EMI in the low cellular frequency bands 15 pF capacitor with self-resonant frequency in the 1700/1800/1900 MHz range (as Murata GRM1555C1H150J), to filter EMI in the high cellular frequency bands 10 nF capacitor (e.g. Murata GRM155R71C103K), to filter digital logic noise from clocks and data 100 nF capacitor (e.g. Murata GRM155R61C104K), to filter digital logic noise from clocks and data An additional capacitor is recommended to avoid undershoot and overshoot at the start and at the end of RF transmission:
10 F capacitor, or greater capacitor, with low ESR (e.g. Murata GRM188R60J106ME47) An additional series ferrite bead is recommended for additional RF noise filtering, in particular if the application device integrates an internal antenna:
Ferrite bead specifically designed for EMI suppression in GHz band (e.g. Murata BLM18EG221SN1), placed as close as possible to the VCC pins of the module, implementing the circuit described in Figure 26, to filter out EMI in all the cellular bands C1 C2 C3 C4 C5 FB1 Figure 26: Suggested design to reduce ripple / noise on VCC, highly recommended when using an integrated antenna Reference Description Part number - Manufacturer 68 pF capacitor ceramic C0G 0402 5% 50 V GRM1555C1H680JA16 - Murata 15 pF capacitor ceramic C0G 0402 5% 50 V GRM1555C1H150JB01 - Murata 10 nF capacitor ceramic X7R 0402 10% 16 V GRT155R71C103KE01 - Murata 100 nF capacitor ceramic X7R 0402 10% 16 V GCM155R71C104KA55 - Murata 10 F capacitor ceramic X5R 0603 20% 6.3 V GRM188R60J106ME47 - Murata Chip Ferrite bead EMI filter for GHz band noise 220 at 100 MHz, 260 at 1 GHz, 2000 mA BLM18EG221SN1 - Murata Table 14: Suggested components to reduce ripple / noise on VCC The necessity of each part depends on the specific design, but it is recommended to provide all the parts described in Figure 26 / Table 14 if the application device integrates an internal antenna.

Higher protection level can be required if the line is externally accessible on the application board, e.g. if accessible battery connector is directly connected to the supply pins. Higher protection level can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor) close to accessible point. 2.2.1.10 Guidelines for VCC supply layout design Good connection of the module VCC pins with DC supply source is required for correct RF performance. Guidelines are summarized in the following list:
All the available VCC pins must be connected to the DC source. VCC connection must be as wide as possible and as short as possible. Any series component with Equivalent Series Resistance (ESR) greater than few milliohms must be avoided. VCC connection must be routed through a PCB area separated from RF lines / parts, sensitive analog signals and sensitive functional units: it is good practice to interpose at least one layer of PCB ground between the VCC track and other signal routing. VCC connection must be routed as far as possible from the antenna, in particular if embedded in the application device: see Figure 27. Coupling between VCC and digital lines must be avoided. The tank bypass capacitor for current spikes smoothing described in section 2.2.1.9 should be placed close to the VCC pins. If the main DC source is a switching DC-DC converter, place the large capacitor close to the DC-DC output and minimize VCC track length. Otherwise consider using separate capacitors for DC-DC converter and module. The bypass capacitors in the pF range described in Figure 26 and Table 14 should be placed as close as possible to the VCC pins, where the VCC line narrows close to the module input pins, improving the RF noise rejection in the band centered on the self-resonant frequency of the pF capacitors. This is highly recommended if the application device integrates an internal antenna. Since VCC input provides the supply to RF power amplifiers, voltage ripple at high frequency may result in unwanted spurious modulation of transmitter RF signal. This is more likely to happen with switching DC-DC converters, in which case it is better to select the highest operating frequency for the switcher and add a large L-C filter before connecting to the SARA-R5 series modules in the worst case. Shielding of switching DC-DC converter circuit, or at least the use of shielded inductors for the switching DC-DC converter, may be considered since all switching power supplies may potentially generate interfering signals as a result of high-frequency high-power switching. If VCC is protected by transient voltage suppressor to ensure that the voltage maximum ratings are not exceeded, place the protecting device along the path from the DC source toward the module, preferably closer to the DC source (otherwise protection function may be compromised).

It significantly reduces EMC issues and provides a thermal heat sink for the module. Connect each GND pin with application board solid GND layer. It is strongly recommended that each GND pad surrounding VCC pins have one or more dedicated via down to the application board solid ground layer. The VCC supply current flows back to main DC source through GND as ground current: provide adequate return path with suitable uninterrupted ground plane to main DC source. It is recommended to implement one layer of the application PCB as GND plane as wide as possible. If the application board is a multilayer PCB, then all the layers should be filled with GND plane as much as possible and each GND area should be connected together with complete via stack down to the main ground layer of the board. Use as many vias as possible to connect the ground planes. Provide a dense line of vias at the edges of each GND area, in particular along RF and high speed lines. If the whole application device is composed by more than one PCB, then it is required to provide a good and solid ground connection between the GND areas of all the different PCBs. Good grounding of GND pads also ensures thermal heat sink. This is critical during connection, when the real network commands the module to transmit at maximum power: correct grounding helps prevent module overheating. 2.2.2 Generic digital interfaces supply output (V_INT) 2.2.2.1 Guidelines for V_INT circuit design SARA-R5 series modules provide the V_INT generic digital interfaces 1.8 V supply output, which can be mainly used to:
Indicate when the module is switched on and it is not in the deep-sleep power saving mode Supply external devices, as voltage translators, instead of using an external discrete regulator
(e.g. see 2.6.1) Pull-up SIM detection signal (see section 2.5 for more details) Do not apply loads which might exceed the maximum available current from V_INT supply (see SARA-R5 series data sheet [1]) as this can cause malfunctions in internal circuitry. V_INT can only be used as an output: do not connect any external supply source on V_INT. ESD sensitivity rating of the V_INT supply pin is 1 kV (HBM according to JESD22-A114). Higher protection level could be required if the line is externally accessible and it can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG) close to accessible point. It is recommended to monitor the V_INT pin to sense the end of the internal switch-off sequence of SARA-R5 series modules: VCC supply can be removed only after V_INT goes low. It is recommended to provide direct access to the V_INT pin on the application board by means of an accessible test point directly connected to the V_INT pin. 2.2.2.2 Guidelines for V_INT layout design V_INT digital interfaces supply output is generated by an integrated switching step-down converter, used internally to supply the digital interfaces. Because of this, it can be a source of noise: avoid coupling with sensitive signals.

If connecting the PWR_ON input to a push button, the pin will be externally accessible on the application device. According to EMC/ESD requirements of the application, an additional ESD protection should be provided close to the accessible point, as described in Figure 28 and Table 15. ESD sensitivity rating of the PWR_ON pin is 1 kV (Human Body Model according to JESD22-A114). Higher protection level can be required if the line is externally accessible on the application board, e.g. if an accessible push button is directly connected to PWR_ON pin, and it can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor) close to the accessible point. An open drain or open collector output is suitable to drive the PWR_ON input from an application processor, as described in Figure 28. PWR_ON input pin should not be driven high by an external device, as it may cause start up issues.

It is required to ensure that the voltage level is well defined during operation and no transient noise is coupled on this line, otherwise the module might detect a spurious power-on request.

If connecting the RESET_N input to a push button, the pin will be externally accessible on the application device. According to EMC/ESD requirements of the application, an additional ESD protection device (e.g. the EPCOS CA05P4S14THSG varistor) should be provided close to accessible point on the line connected to this pin, as described in Figure 29 and Table 16. ESD sensitivity rating of the RESET_N pin is 1 kV (HBM according to JESD22-A114). Higher protection level can be required if the line is externally accessible on the application board, e.g. if an accessible push button is directly connected to the RESET_N pin, and it can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor) close to accessible point. An open drain output or open collector output is suitable to drive the RESET_N input from an application processor, as described in Figure 29.

Ensure that the voltage level is well defined during operation and no transient noise is coupled on this line, otherwise the module might detect a spurious reset request. It is recommended to keep the connection line to RESET_N pin as short as possible.

the ANT pin represents the cellular RF input/output for cellular signals transmission and reception. SARA-R510M8S modules provide also a GNSS RF interface for connecting the external GNSS antenna: the ANT_GNSS pin represents the GNSS RF input for GNSS signals reception. The ANT and ANT_GNSS pins have a nominal characteristic impedance of 50 and must be connected to the related physical antenna through a 50 transmission line to allow clean transmission / reception of RF signals. 2.4.1 General guidelines for antenna interfaces 2.4.1.1 Guidelines for ANT and ANT_GNSS pins RF connection design The GNSS antenna RF interface is not supported by SARA-R500S and SARA-R510S modules. A clean transition between the ANT and ANT_GNSS pads and the application board PCB must be provided, implementing the following design-in guidelines for the layout of the application PCB close to the ANT and ANT_GNSS pads:
On a multilayer board, the whole layer stack below the RF connections should be free of digital lines Increase GND keep-out (i.e. clearance, a void area) around the ANT and ANT_GNSS pads, on the top layer of the application PCB, to at least 250 m up to adjacent pads metal definition and up to 400 m on the area below the module, to reduce parasitic capacitance to ground, as described in the left picture in Figure 30 Add GND keep-out (i.e. clearance, a void area) on the buried metal layer below the ANT and ANT_GNSS pads if the top-layer to buried layer dielectric thickness is below 200 m, to reduce parasitic capacitance to ground, as described in the right picture in Figure 30 Figure 30: GND keep-out area on top layer around RF pad and on very close buried layer below RF pad (ANT / ANT_GNSS) Refer to section 2.4.2.3 for the description of the antenna trace design implemented on the u-blox host printed circuit board used for conformity assessment of SARA-R5 series surface-mounted modules for regulatory type approvals such as FCC United States, ISED Canada, RED Europe, etc. UBX-19041356 - R03 Confidential Design-in Page 52 of 123 GND clearance on top layer around RF pad on buried layer very close to top layer GND clearance below RF pad Min. 250 m RF pad Min. 400 m GND SARA-R5 series - System integration manual 2.4.1.2 Guidelines for RF transmission lines design The GNSS antenna RF interface is not supported by SARA-R500S and SARA-R510S modules. Any RF transmission line, such as the ones from the ANT and ANT_GNSS pads up to the related antenna connector or up to the related internal antenna pad, must be designed so that the characteristic impedance is as close as possible to 50 . RF transmission lines can be designed as a micro strip (consists of a conducting strip separated from a ground plane by a dielectric material) or a strip line (consists of a flat strip of metal which is sandwiched between two parallel ground planes within a dielectric material). The micro strip, implemented as a coplanar waveguide, is the most common configuration for printed circuit board. Figure 31 and Figure 32 provide two examples of suitable 50 coplanar waveguide designs. The first example of RF transmission line can be implemented in case of 4-layer PCB stack-up herein described, and the second example of RF transmission line can be implemented in case of 2-layer PCB stack-up herein described. Figure 31: Example of 50 coplanar waveguide transmission line design for the described 4-layer board layup Figure 32: Example of 50 coplanar waveguide transmission line design for the described 2-layer board layup If the two examples do not match the application PCB stack-up, then the 50 characteristic impedance calculation can be made using the HFSS commercial finite element method solver for electromagnetic structures from Ansys Corporation, or using freeware tools like Avago / Broadcom AppCAD (https://www.broadcom.com/appcad) taking care of the approximation formulas used by the tools for the impedance computation. To achieve a 50 characteristic impedance, the transmission line width must be chosen due to:
the thickness of the transmission line itself (e.g. 35 m in the example of Figure 31 and Figure 32) the thickness of the dielectric material between the top layer (where the line is routed) and the inner closer layer implementing the ground plane (e.g. 270 m in Figure 31, 1510 m in Figure 32) the dielectric constant of the dielectric material (e.g. dielectric constant of the FR-4 dielectric material in Figure 31 and Figure 32) the gap from the transmission line to the adjacent ground plane on the same layer of the transmission line (e.g. 500 m in Figure 31, 400 m in Figure 32) UBX-19041356 - R03 Confidential Design-in Page 53 of 123 500 m 380 m 500 m L1 copper FR-4 dielectric L2 copper FR-4 dielectric L3 copper FR-4 dielectric L4 copper 35 m 270 m 35 m 760 m 35 m 270 m 35 m 400 m 1200 m 400 m L1 copper FR-4 dielectric L2 copper 35 m 1510 m 35 m SARA-R5 series - System integration manual If the distance between the transmission line and the adjacent GND area (on the same layer) does not exceed 5 times the width of the line, use the Coplanar Waveguide model for the 50 calculation. Additionally to the 50 impedance, the following guidelines are recommended for transmission lines:
Minimize the transmission line length: the insertion loss should be minimized as much as possible, in the order of a few tenths of a dB, Add GND keep-out (i.e. clearance, a void area) on buried metal layers below any pad of component present on the RF transmission lines, if top-layer to buried layer dielectric thickness is below 200 m, to reduce parasitic capacitance to ground, The transmission lines width and spacing to GND must be uniform and routed as smoothly as possible: avoid abrupt changes of width and spacing to GND, Add GND stitching vias around transmission lines, as described in Figure 33, Ensure solid metal connection of the adjacent metal layer on the PCB stack-up to main ground layer, providing enough vias on the adjacent metal layer, as described in Figure 33, Route RF transmission lines far from any noise source (as switching supplies and digital lines) and from any sensitive circuit (as USB), Avoid stubs on the transmission lines, Avoid signal routing in parallel to transmission lines or crossing the transmission lines on buried metal layer, Do not route microstrip lines below discrete component or other mechanics placed on top layer Two examples of a suitable RF circuit design for ANT pin are illustrated in Figure 33, where the cellular antenna detection circuit is not implemented (if the cellular antenna detection function is required by the application, follow the guidelines for circuit and layout implementation detailed in section 2.4.4):
In the first example shown on the left, the ANT pin is directly connected to an SMA connector by means of a suitable 50 transmission line, designed with the appropriate layout. In the second example shown on the right, the ANT pin is connected to an SMA connector by means of a suitable 50 transmission line, designed with the appropriate layout, with an additional high pass filter to improve the ESD immunity at the antenna port. (The filter consists of a suitable series capacitor and shunt inductor, for example the Murata GRM1555C1H150JB01 15 pF capacitor and the Murata LQG15HN39NJ02 39 nH inductor with SRF ~1 GHz.). Figure 33: Example of circuit and layout for ANT RF circuits on the application board Refer to section 2.4.2.3 for the description of the antenna trace design implemented on the u-blox host printed circuit board used for conformity assessment of SARA-R5 series surface-mounted modules for regulatory type approvals such as FCC United States, ISED Canada, RED Europe, etc. UBX-19041356 - R03 Confidential Design-in Page 54 of 123 SARA module SARA module SMA connector High-pass filter to improve ESD immunity SMA connector SARA-R5 series - System integration manual 2.4.1.3 Guidelines for RF termination design The GNSS antenna RF interface is not supported by SARA-R500S and SARA-R510S modules. The RF termination must provide a characteristic impedance of 50 as well as the RF transmission line up to the RF termination, to match the characteristic impedance of ANT and ANT_GNSS ports. However, real antennas do not have a perfect 50 load on all the supported frequency bands. So to reduce as much as possible any performance degradation due to antenna mismatching, the RF termination must provide optimal return loss (or VSWR) figures over all the operating frequencies, as summarized in Table 6 and Table 7. If an external antenna is used, the antenna connector represents the RF termination on the PCB:
Use a suitable 50 connector providing a clean PCB-to-RF-cable transition. Strictly follow the connector manufacturers recommended layout, for example:
o SMA Pin-Through-Hole connectors require a GND keep-out (i.e. clearance, a void area) on all the layers around the central pin up to the annular pads of the four GND posts, as illustrated in Figure 33 or in Figure 39. o U.FL surface mounted connectors require no conductive traces (i.e. clearance, a void area) in the area below the connector between the GND land pads, as illustrated in 34. Figure 34: U.FL surface mounted connector mounting pattern layout Cut out the GND layer under the RF connector and close to any buried vias, to remove stray capacitance and thus keep the RF line at 50 , e.g. the active pad of U.FL connector needs to have a GND keep-out (i.e. clearance, a void area) at least on the first inner layer to reduce parasitic capacitance to ground. If an integrated antenna is used, the integrated antenna represents the RF terminations. The following guidelines should be followed:
Use an antenna designed by an antenna manufacturer providing the best possible return loss. Provide a ground plane large enough according to the relative integrated antenna requirements. The ground plane of the application PCB can be reduced down to a minimum size that must be similar to one quarter of wavelength of the minimum frequency that needs to be radiated. As numerical example, It is highly recommended to strictly follow the detailed and specific guidelines provided by the antenna manufacturer regarding correct installation and deployment of the antenna system, including the PCB layout and matching circuitry. Frequency = 617 MHz Wavelength 48 cm Minimum GND plane size 12 cm Further to the custom PCB and product restrictions, the antenna may require a tuning to comply with all the applicable required certification schemes. It is recommended to consult the antenna manufacturer for antenna matching design-in guidelines relative to the custom application. Additionally, these recommendations regarding the antenna system placement must be followed:
Do not place the antennas within a closed metal case. Do not place the cellular antenna in close vicinity to the end user since the emitted radiation in human tissue is restricted by regulatory requirements. Place the antennas as far as possible from VCC supply line and related parts (see also Figure 27), from high speed digital lines (as USB) and from any possible noise source. UBX-19041356 - R03 Confidential Design-in Page 55 of 123 SARA-R5 series - System integration manual Place the antenna far from sensitive analog systems or employ countermeasures to reduce EMC or EMI issues. Be aware of interaction between co-located RF systems since the LTE transmitted power may interact or disturb the performance of companion systems (see also section 1.7.4). Refer to section 2.4.2.3 for the description of the antenna trace design implemented on the u-blox host printed circuit board used for conformity assessment of SARA-R5 series surface-mounted modules for regulatory type approvals such as FCC United States, ISED Canada, RED Europe, etc. 2.4.2 Cellular antenna RF interface (ANT) 2.4.2.1 Guidelines for antenna selection and design The antenna is the most critical component to be evaluated. Designers must take care of the antenna from all perspective at the very start of the design phase when the physical dimensions of the application board are under analysis/decision, since the cellular compliance of the device integrating SARA-R5 series modules with all the applicable required certification schemes depends on antennas radiating performance. Cellular antennas are typically available as:
External antennas (e.g. linear monopole):
o External antennas basically do not imply physical restriction to the design of the PCB where the SARA-R5 series module is mounted. o The radiation performance mainly depends on the antennas. It is required to select antennas with optimal radiating performance in the operating bands. o RF cables should be carefully selected to have minimum insertion losses. Additional insertion loss will be introduced by low quality or long cable. Large insertion loss reduces both transmit and receive radiation performance. o A high quality 50 RF connector provides a clean PCB-to-RF-cable transition. It is recommended to strictly follow the layout and cable termination guidelines provided by the connector manufacturer. Integrated antennas (e.g. PCB antennas such as patches or ceramic SMT elements):
o Internal integrated antennas imply physical restriction to the design of the PCB: Integrated antenna excites RF currents on its counterpoise, typically the PCB ground plane of the device that becomes part of the antenna: its dimension defines the minimum frequency that can be radiated. Therefore, the ground plane can be reduced down to a minimum size that should be similar to the quarter of the wavelength of the minimum frequency that needs to be radiated, given that the orientation of the ground plane relative to the antenna element must be considered. As numerical example, the physical restriction to the PCB design can be considered as following:
Frequency = 617 MHz Wavelength 48 cm Minimum GND plane size 12 cm o o Radiation performance depends on the whole PCB and antenna system design, including product mechanical design and usage. Antennas should be selected with optimal radiating performance in the operating bands according to the mechanical specifications of the PCB and the whole product. It is recommended to select a custom antenna designed by an antennas manufacturer if the required ground plane dimensions are very small (e.g. less than 6.5 cm long and 4 cm wide). The antenna design process should begin at the start of the whole product design process. It is highly recommended to strictly follow the detailed and specific guidelines provided by the antenna manufacturer regarding correct installation and deployment of the antenna system, including PCB layout and matching circuitry. o UBX-19041356 - R03 Confidential Design-in Page 56 of 123 SARA-R5 series - System integration manual o Further to the custom PCB and product restrictions, antennas may require tuning to obtain the required performance for compliance with all the applicable required certification schemes. It is recommended to consult the antenna manufacturer for the design-in guidelines for antenna matching relative to the custom application. In both of cases, selecting external or internal antennas, these recommendations should be observed:
Select an antenna providing optimal return loss / VSWR figure over all the operating frequencies. Select an antenna providing optimal efficiency figure over all the operating frequencies. Select an antenna providing appropriate gain figure (i.e. combined directivity and efficiency figure) so that the RF radiation intensity do not exceed the regulatory limits specified in some countries:

Manufacturers of mobile or fixed devices incorporating SARA-R5 series modules are authorized to use the FCC United States Grants and ISED Canada Certificates of SARA-R5 series modules for their own final host products if, as per FCC KDB 996369, the antenna trace design implemented on the host PCB is electrically equivalent to the antenna trace design implemented on the u-blox host PCB used for regulatory type approvals of SARA-R5 series modules, described in this section. In case of antenna trace design change, an FCC Class II Permissive Change and/or ISED Class IV Permissive Change application is required to be filed by the grantee, or the host manufacturer can take responsibility through the change in FCC ID and/or the ISES Multiple Listing (new application) procedure followed by an FCC C2PC and/or ISED C4PC application. The antenna trace design is implemented on the u-blox host PCB as illustrated in Figure 35, using the parts listed in Table 20, with the support of the additional optional antenna detection capability.

The antenna and its placement are critical system factors for accurate GNSS reception. Use of a ground plane will minimize the effects of ground reflections and enhance the antenna efficiency. A ground plane with a minimum diameter of 10 centimeter is recommended. Exercise care with rover vehicles that emit RF energy from motors etc. as interference may extend into the GNSS band and couple into the GNSS antenna suppressing the wanted signal. Since SARA-R510M8S modules already include an internal SAW filter followed by an additional LNA before the u-blox M8 GNSS chipset (as illustrated in Figure 4), they are optimized to work with passive or active antennas without requiring additional external circuitry. 2.4.3.1 Guidelines for applications with a passive antenna If a GNSS passive antenna with high gain and good sky view is used, together with a short 50 line between antenna and receiver, and no jamming sources affect the GNSS passive antenna, the circuit illustrated in Figure 40 can be used. This provides the minimum BoM cost and minimum board space. Figure 40: Minimum circuit with GNSS passive antenna Where best performance needs to be achieved, and improved jamming immunity is needed due to strong out-band jammers close to the GNSS antenna (e.g. the cellular antenna), consider adding an external SAW filter (as for example Murata SAFFB1G56AC0F0A, or SAFFB1G56AC0F7F) close to the GNSS passive antenna, followed by an external LNA (as for example Maxim MAX2659ELT+, JRC New Japan Radio NJG1143UA2, NXP BGU8006, Infineon BGA524N6), as illustrated in Figure 41.

Noise figure (sensitivity) Selectivity and linearity (robustness against jamming) Robustness against RF power Depending on the characteristics of the supply source (DC/DC regulator, linear LDO regulator or other) used to supply the external LNA, make sure some good filtering is in place for the external LNA supply because of the noise on the external LNA supply line can affect the performance of the LNA itself:
consider adding a proper series ferrite bead (as for example the Murata BLM15HD182SN1, Murata BLM15HD102SN1, TDK MMZ1005F121E, or TDK MMZ1005A121E) and a proper decoupling capacitor to ground (as for example the Murata GCM1555C1H270JA16, 22 pF capacitor) at the input of the external LNA supply line. It should be noted anyway that the insertion loss of the filter directly affects the system noise figure and hence the system performance. The selected SAW filter has to provide very low loss in the GNSS pass-band, beside providing very large attenuation in the out-band jammers cellular frequency bands
(as for example the Murata SAFFB1G56AC0F0A, or the Murata SAFFB1G56AC0F7F). Table 21 lists examples of passive antennas to be used with SARA-R510M8S modules.

UBX-19041356 - R03 Confidential Design-in Page 63 of 123 SARA-R5 series - System integration manual 2.4.3.2 Guidelines for applications with an active antenna Active antennas for GNSS applications are usually powered through a DC bias on the RF cable. A simple bias-T, as shown in Figure 42, can be used to add this DC current to the RF signal line. The inductance L is responsible for isolating the RF path from the DC path, while Rbias and C form a low pass filter to remove high frequency noise from the DC supply. L should be also selected to pass the DC fault current in case the antenna connection is shorted.

When antenna detection is forced by the +UANTR AT command (see the SARA-R5 series AT commands manual [1]), the ANT_DET pin generates a DC current measuring the resistance (R2) from the antenna connector (J1) provided on the application board to GND. DC blocking capacitors are needed at the ANT pin (C2) and at the antenna radiating element (C4) to decouple the DC current generated by the ANT_DET pin. Choke inductors with a Self-Resonance Frequency (SRF) in the range of 1 GHz are needed in series at the ANT_DET pin (L1) and in series at the diagnostic resistor (L3), to avoid a reduction of the RF performance of the system, improving the RF isolation of the load resistor. Resistor on the ANT_DET path (R1) is needed for accurate measurements through the +UANTR AT command. It also acts as an ESD protection. Additional components (C1 and D1 in Figure 43) are needed at the ANT_DET pin as ESD protection. Additional high pass filter (C3 and L2 in Figure 43) is provided as ESD immunity improvement The ANT pin must be connected to the antenna connector by means of a transmission line with nominal characteristics impedance as close as possible to 50 . UBX-19041356 - R03 Confidential Design-in Page 65 of 123 SARA-R5 series C3 C2 Z0= 50 Z0= 50 Z0= 50 ohm ANT 56 L2 J1 Antenna cable ANT_DET 62 GND R1 L1 C1 D1 Diagnostic circuit Radiating element C4 L3 R2 Application board Antenna assembly SARA-R5 series - System integration manual The DC impedance at RF port for some antennas may be a DC open (e.g. linear monopole) or a DC short to reference GND (e.g. PIFA antenna). For those antennas, without the diagnostic circuit of Figure 43, the measured DC resistance is always at the limits of the measurement range (respectively open or short), and there is no mean to distinguish between a defect on antenna path with similar characteristics (respectively: removal of linear antenna or RF cable shorted to GND for PIFA antenna). Furthermore, any other DC signal injected to the RF connection from ANT connector to radiating element will alter the measurement and produce invalid results for antenna detection. It is recommended to use an antenna with a built-in diagnostic resistor in the range from 5 k to 30 k to assure good antenna detection functionality and avoid a reduction of module RF performance. The choke inductor should exhibit a parallel Self-Resonance Frequency (SRF) in the range of 1 GHz to improve the RF isolation of load resistor. For example:
Consider an antenna with built-in DC load resistor of 15 k. Using the +UANTR AT command, the module reports the resistance value evaluated from the antenna connector provided on the application board to GND:
Reported values close to the used diagnostic resistor nominal value (i.e. values from 13 k to 17 k if a 15 k diagnostic resistor is used) indicate that the antenna is correctly connected. Values close to the measurement range maximum limit or an open-circuit over range report (see the SARA-R5 series AT commands manual [2]) means that the antenna is not connected or the RF cable is broken. Reported values below the measurement range minimum limit highlights a short to GND at antenna or along the RF cable. Measurement inside the valid measurement range and outside the expected range may indicate an unclean connection, a damaged antenna or incorrect value of the antenna load resistor for diagnostics. Reported value could differ from the real resistance value of the diagnostic resistor mounted inside the antenna assembly due to antenna cable length, antenna cable capacity and the used measurement method. If the antenna detection function is not required by the customer application, the ANT_DET pin can be left not connected and the ANT pin can be directly connected to the antenna connector by means of a 50 transmission line as described in Figure 33. UBX-19041356 - R03 Confidential Design-in Page 66 of 123 SARA-R5 series - System integration manual 2.4.4.2 Guidelines for ANT_DET layout design Figure 44 describes the recommended layout for the cellular antenna detection circuit to be provided on the application board to achieve antenna detection functionality, implementing the recommended schematic described in the previous Figure 43 and Table 23:
The ANT pin must be connected to the cellular antenna connector by means of a 50 transmission line, implementing the design guidelines described in section 2.4.2 and the recommendations of the SMA connector manufacturer. DC blocking capacitor at ANT pin (C2) must be placed in series to the 50 RF line. The ANT_DET pin must be connected to the 50 transmission line by means of a sense line. Choke inductor in series at the ANT_DET pin (L1) must be placed so that one pad is on the 50 transmission line and the other pad represents the start of the sense line to the ANT_DET pin. The additional components (R1, C1 and D1) on the ANT_DET line must be placed as ESD protection. The additional high pass filter (C3 and L2) on the ANT line is placed as ESD immunity improvement Figure 44: Suggested layout for antenna detection circuit on application board 2.4.5 Cellular antenna dynamic tuning control interface SARA-R5 series modules support a wide range of frequencies, from 600 MHz to 2200 MHz. To provide more efficient antenna designs over a wide bandwidth, I2S_TXD and I2S_WA pins can be configured to change their output value according to the LTE band used by the module (see sections 1.11 and 2.8). These pins, paired with an external antenna tuner IC or RF switch, can be used to:
tune antenna impedance to reduce power losses due to mismatch tune antenna aperture to improve total antenna efficiency select the optimal antenna for each operating band Table 24 reports the antenna dynamic tuning pins setting at the related module operating band.

The module controls an RF switch which is responsible for selecting the appropriate matching element for the operating band. Table 25 reports suggested components implementing the SP4T RF switch functionality. In Figure 45(a), tuning the antenna impedance optimizes the power delivered into the antenna by dynamically adjusting the RF impedance seen by ANT pin of SARA-R5 series module. By creating a tuned matching network for each operating band, the total radiated power (TRP) and the total isotropic sensitivity (TIS) metrics are improved. In Figure 45(b), antenna aperture tuning enables higher antenna efficiency over a wide frequency range. The dynamically tunable components are added to the antenna structure itself, thereby modifying the effective electrical length of the radiating element. Thus the resonant frequency of the antenna is shifted into the modules operating frequency band. Aperture tuning optimizes radiation efficiency, insertion loss, isolation and rejection levels of the antenna. Figure 45: Examples of schematics for cellular antenna dynamic impedance tuning (a) and aperture tuning (b). Refer to the antenna datasheet and/or manufacturer for proper values of matching components Z1, Z2, Z3, L1, L2, C1, C2. These components should have low losses to avoid degrading the radiating efficiency of the antenna, thereby hindering the positive effects of dynamic tuning.

Removable UICC / SIM card contacts mapping is defined by ISO/IEC 7816 and ETSI TS 102 221 as follows:
Contact C1 = VCC (Supply) Contact C2 = RST (Reset) Contact C3 = CLK (Clock) Contact C4 = AUX1 (Auxiliary contact) Contact C5 = GND (Ground) Contact C6 = VPP (Programming supply) Contact C7 = I/O (Data input/output) Contact C8 = AUX2 (Auxiliary contact) It must be connected to VSIM It must be connected to SIM_RST It must be connected to SIM_CLK It must be left not connected It must be connected to GND It can be left not connected It must be connected to SIM_IO It must be left not connected A removable SIM card can have 6 contacts (C1, C2, C3, C5, C6, C7) or 8 contacts, also including the auxiliary contacts C4 and C8. Only 5 contacts are required and must be connected to the module SIM interface. Removable SIM cards are suitable for applications requiring a change of SIM card during the product lifetime. A SIM card holder can have 6 or 8 positions if a mechanical card presence detector is not provided, or it can have 6+2 or 8+2 positions if two additional pins relative to the normally-open mechanical switch integrated in the SIM connector for the mechanical card presence detection are provided. Select a SIM connector providing 6+2 or 8+2 positions if the optional SIM detection feature is required by the custom application, otherwise a connector without integrated mechanical presence switch can be selected. Surface-Mounted UICC / SIM chip contact mapping (M2M UICC Form Factor) is defined by the ETSI TS 102 671 as:
Case pin 8 = UICC contact C1 = VCC (Supply) Case pin 7 = UICC contact C2 = RST (Reset) Case pin 6 = UICC contact C3 = CLK (Clock) Case pin 5 = UICC contact C4 = AUX1 (Aux. contact) It must be left not connected It must be connected to GND Case pin 1 = UICC contact C5 = GND (Ground) It can be left not connected Case pin 2 = UICC contact C6 = VPP (Progr. supply) It must be connected to SIM_IO Case pin 3 = UICC contact C7 = I/O (Data I/O) Case pin 4 = UICC contact C8 = AUX2 (Aux. contact) It must be left not connected It must be connected to VSIM It must be connected to SIM_RST It must be connected to SIM_CLK A Surface-Mounted SIM chip has 8 contacts and can also include the auxiliary contacts C4 and C8 for other uses, but only 6 contacts are required and must be connected to the module SIM card interface as described above. Surface-Mounted SIM chips are suitable for M2M applications where it is not required to change the SIM once installed.

Provide a 100 nF bypass capacitor (e.g. Murata GRM155R71C104K) on SIM supply line, close to the relative pad of the SIM connector, to prevent digital noise. Provide a bypass capacitor of about 22 pF to 47 pF (e.g. Murata GCM1555C1H470JA16) on each SIM line, very close to each related pad of the SIM connector, to prevent RF coupling especially in case the RF antenna is placed closer than 10 - 30 cm from the SIM card holder. Provide a very low capacitance (i.e. less than 10 pF) ESD protection (e.g. Tyco PESD0402-140) on each externally accessible SIM line, close to each relative pad of the SIM connector. ESD sensitivity rating of the SIM interface pins is 1 kV (HBM). So that, according to EMC/ESD requirements of the custom application, higher protection level can be required if the lines are externally accessible on the application device. Limit capacitance and series resistance on each SIM signal to match the requirements for the SIM interface regarding maximum allowed rise time on the lines.

(SW1 pin in Figure 48) to V_INT 1.8 V supply output by means of a strong pull-up resistor (e.g. 1 k, as R1 in Figure 48) Provide a 100 nF bypass capacitor (e.g. Murata GRM155R71C104K) at the SIM supply line (VSIM), close to the related pad of the SIM connector, to prevent digital noise. Provide a bypass capacitor of about 22 pF to 47 pF (e.g. Murata GCM1555C1H470JA16) on each SIM line (VSIM, SIM_CLK, SIM_IO, SIM_RST), very close to each related pad of the SIM connector, to prevent RF coupling especially in case the RF antenna is placed closer than 10 - 30 cm from the SIM card holder. Provide a low capacitance (i.e. less than 10 pF) ESD protection (e.g. Tyco Electronics PESD0402-140) on each externally accessible SIM line, close to each related pad of the SIM connector. The ESD sensitivity rating of SIM interface pins is 1 kV (HBM according to JESD22-A114), so that, according to the EMC/ESD requirements of the custom application, higher protection level can be required if the lines are externally accessible. Limit capacitance and series resistance on each SIM signal to match the requirements for the SIM interface regarding maximum allowed rise time on the lines.

In the first case, the long connection can cause the radiation of some harmonics of the digital data frequency as any other digital interface. It is recommended to keep the traces short and avoid coupling with RF lines or sensitive analog inputs. In the second case, the same harmonics can be picked up and create self-interference that can reduce the sensitivity of LTE receiver channels (and/or GNSS channels, for SARA-R510M8S modules) whose carrier frequency is coincidental with harmonic frequencies. It is strongly recommended to place the RF bypass capacitors suggested in Figure 46, Figure 47, Figure 48 near the SIM connector. In addition, since the SIM card is typically accessed by the end user, it can be subjected to ESD discharges. Add adequate ESD protection as suggested to protect module SIM pins near the SIM connector. Limit capacitance and series resistance on each SIM signal to match the SIM specifications. The connections should always be kept as short as possible. Avoid coupling with any sensitive analog circuit, since the SIM signals can cause the radiation of some harmonics of the digital data frequency.

Consider the value of the pull-down / pull-up integrated at the input of the module (DCE) for the correct selection of the voltage divider resistance values. Make sure that any DTE signal connected to the module is tri-stated or set low when the module is in power-down mode and during the module power-on sequence (at least until the activation of the V_INT supply output of the module), to avoid latch-up of circuits and allow a clean boot of the module (see the remark below). Moreover, the voltage scaling from any 1.8 V output of the cellular module (DCE) to the corresponding 3.0 V input of the application processor (DTE) can be implemented by means of an appropriate low-cost non-inverting buffer with open drain output. The non-inverting buffer should be supplied by the V_INT supply output of the cellular module. Consider the value of the pull-up integrated at each input of the DTE (if any) and the baud rate required by the application for the appropriate selection of the resistance value for the external pull-up biased by the application processor supply rail. Do not apply voltage to any UART interface pin before the switch-on of the UART supply source
(V_INT), to avoid latch-up of circuits and allow a clean boot of the module. If the external signals connected to the cellular module cannot be tri-stated or set low, insert a multi-channel digital switch (e.g. TI SN74CB3Q16244, TS5A3159, or TS5A63157) between the two-circuit connections and set to high impedance before V_INT switch-on. ESD sensitivity rating of the UART interface pins is 1 kV (Human Body Model according to JESD22-A114). Higher protection levels could be required if the lines are externally accessible and it can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor array) close to the accessible points. 2.6.1.2 Guidelines for UART layout design The UART serial interface requires the same consideration regarding electro-magnetic interference as any other digital interface. Keep the traces short and avoid coupling with RF line or sensitive analog inputs, since the signals can cause the radiation of some harmonics of the digital data frequency.

USB pull-up or pull-down resistors and external series resistors on USB_D+ and USB_D- lines as required by the USB 2.0 specification [4] are part of the module USB pins driver and do not need to be externally provided. Figure 61: SARA-R5 series modules USB application circuit providing access for diagnostic purpose The USB interface pins ESD sensitivity rating is 1 kV (Human Body Model according to JESD22-

Higher protection level could be required if the lines are externally accessible and it can be achieved by mounting a very low capacitance (i.e. less or equal to 1 pF) ESD protection (e.g. Tyco Electronics PESD0402-140 ESD protection device) on the lines connected to these pins, close to accessible points. It is recommended to provide accessible test points directly connected to the USB interface pins
(VUSB_DET, USB_D+, USB_D-). 2.6.2.2 Guidelines for USB layout design The characteristic impedance of the USB_D+ / USB_D- lines is specified by the USB 2.0 specification [4]. The most important parameter is the differential characteristic impedance applicable for the odd-mode electromagnetic field, which should be as close as possible to 90 differential. Signal integrity may be degraded if PCB layout is not optimal, especially when the USB signaling lines are very long. Use the following general routing guidelines to minimize signal quality problems:
Route USB_D+ / USB_D- lines as a differential pair Route USB_D+ / USB_D- lines as short as possible Ensure the differential characteristic impedance (Z0) is as close as possible to 90 Ensure the common mode characteristic impedance (ZCM) is as close as possible to 30 Consider design rules for USB_D+ / USB_D- similar to RF transmission lines, whether coupled differential micro-strip or buried stripline: avoid any stubs, abrupt change of layout, and route on clear PCB area UBX-19041356 - R03 Confidential Design-in Page 81 of 123 TestPoint TestPoint TestPoint SARA-R5 series 17 VUSB_DET 29 USB_D+

The DDC I2C-bus master interface can be used to communicate with u-blox GNSS receivers and other external I2C-bus slaves as an audio codec. The SDA and SCL pins of the module are open drain output as per I2C bus specifications [9], and they have internal pull-up resistors to the V_INT 1.8 V supply rail of the module, so there is no need of additional pull-up resistors on the external application board. Capacitance and series resistance must be limited on the bus to match the I2C specifications
(1.0 s is the max allowed rise time on SCL and SDA lines): route connections as short as possible. ESD sensitivity rating of the DDC (I2C) pins is 1 kV (HBM according to JESD22-A114). Higher protection level could be required if the lines are externally accessible and it can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor) close to accessible points. If the pins are not used as DDC bus interface, they can be left unconnected. Connection with u-blox 1.8 V GNSS receivers Figure 64 shows a circuit example for connecting the cellular module to a u-blox 1.8 V GNSS receiver:
The SDA and SCL pins of the cellular module are directly connected to the related pins of the u-blox 1.8 V GNSS receiver. External pull-up resistors are not needed, as they are already integrated in the cellular module. The GPIO2 pin is connected to the active-high enable pin of the voltage regulator that supplies the u-blox 1.8 V GNSS receiver providing the GNSS supply enable function. A pull-down resistor is provided to avoid a switch on of the positioning receiver when the cellular module is switched off or in the reset state. The GPIO3 and GPIO4 pins are directly connected respectively to TXD1 and EXTINT0 pins of the u-blox 1.8 V GNSS receiver providing GNSS data ready and GNSS RTC sharing functions. For additional guidelines regarding the design of applications with u-blox 1.8 V GNSS receivers, see the hardware integration manuals of the u-blox GNSS receivers.

Figure 65 shows an application circuit for connecting the cellular module to a u-blox 3.0 V GNSS receiver:
As the SDA and SCL pins of the cellular module are not tolerant up to 3.0 V, the connection to the related I2C pins of the u-blox 3.0 V GNSS receiver must be provided using a suitable I2C-bus bidirectional voltage translator (e.g. TI TCA9406, which additionally provides the partial power down feature so that the GNSS 3.0 V supply can be ramped up before the V_INT 1.8 V cellular supply). External pull-up resistors are not needed on the cellular module side, as they are already integrated in the cellular module. The GPIO2 is connected to the active-high enable pin of the voltage regulator that supplies the u-blox 3.0 V GNSS receiver providing the GNSS supply enable function. A pull-down resistor is provided to avoid a switch-on of the positioning receiver when the cellular module is switched off or in the reset state. The GPIO3 and GPIO4 pins are connected respectively to the TXD1 and EXTINT0 pins of the u-blox 3.0 V GNSS receiver providing GNSS data ready and GNSS RTC sharing functions, using a suitable unidirectional general purpose voltage translator (e.g. TI SN74AVC2T245, which additionally provides the partial power down feature so that the 3.0 V GNSS supply can be also ramped up before the V_INT 1.8 V cellular supply). For additional guidelines regarding the design of applications with u-blox 3.0 V GNSS receivers, see the hardware integration manuals of the u-blox GNSS receivers.

Keep the traces short and avoid coupling with RF line or sensitive analog inputs, since the signals can cause the radiation of some harmonics of the digital data frequency. 2.7 Audio Audio is not supported by the 00 product version of SARA-R5 series modules. 2.8 General purpose input / output (GPIO) 2.8.1 Guidelines for GPIO circuit design A typical usage of SARA-R5 series modules GPIOs can be the following:
GNSS supply enable function provided by the GPIO2 pin 13 (see section 2.6.5) GNSS data ready function provided by the GPIO3 pin 13 (see section 2.6.5) GNSS RTC sharing function provided by the GPIO4 pin 13 (see section 2.6.5) Network indication provided over GPIO1 pin (see Figure 66 / Table 37 below) Module status / operating mode indication provided by a GPIO pin (see section 1.6.1) SIM card detection provided over GPIO5 pin (see Figure 48 / Table 28 in section 2.5) Antenna dynamic tuning provided over I2S_TXD and I2S_WA pins (see section 2.4.5) Figure 66: Application circuit for network indication provided over GPIO1 Reference Description Part number - Manufacturer 10 k resistor 0402 5% 0.1 W Generic manufacturer 47 k resistor 0402 5% 0.1 W Generic manufacturer 820 resistor 0402 5% 0.1 W Generic manufacturer LED red SMT 0603 NPN BJT transistor LTST-C190KRKT - Lite-on Technology Corporation BC847 - Infineon Table 37: Components for network indication application circuit 13 Not supported by SARA-R510M8S modules UBX-19041356 - R03 Confidential Design-in Page 85 of 123 SARA-R5 series GPIO1 16 Network Indicator R1 3V8 DL1 R3 T1 R2 SARA-R5 series - System integration manual Use transistors with at least an integrated resistor in the base pin or otherwise put a 10 k resistor on the board in series to the GPIO of SARA-R5 series modules. Do not apply voltage to any GPIO of the module before the switch-on of the GPIOs supply (V_INT), to avoid latch-up of circuits and allow a clean module boot. If the external signals connected to the module cannot be tri-stated or set insert a multi-channel digital switch (e.g. TI SN74CB3Q16244, TS5A3159, TS5A63157) between the two-circuit connections and set to high impedance before V_INT switch-on. low, ESD sensitivity rating of the GPIO pins is 1 kV (Human Body Model according to JESD22-A114). Higher protection level could be required if the lines are externally accessible and it can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor array) close to accessible points. If the GPIO pins are not used, they can be left unconnected on the application board. 2.8.2 Guidelines for general purpose input/output layout design The general purpose input / output pins are generally not critical for layout. 2.9 Reserved pin (RSVD) SARA-R5 series modules have a pin reserved for future use, marked as RSVD. This pin is to be left unconnected on the application board. 2.10 Module placement An optimized placement allows minimum RF lines length and closer path from DC source for VCC. Make sure that the module, analog parts and RF circuits are clearly separated from any possible source of radiated energy. In particular, digital circuits can radiate digital frequency harmonics, which can produce electro-magnetic interference that affects the module, analog parts and RF circuits performance. Implement suitable countermeasures to avoid any possible electro-magnetic compatibility issue. Make sure that the module is placed in order to keep the antenna (or antennas, for SARA-R510M8S) as far as possible from VCC supply line and related parts (refer to Figure 27), from high speed digital lines (as USB) and from any possible noise source. Provide enough clearance between the module and any external part: clearance of at least 0.4 mm per side is recommended to let suitable mounting of the parts. The heat dissipation during continuous transmission at maximum power can raise the temperature of the application base-board below the SARA-R5 series modules: avoid placing temperature sensitive devices close to the module.

The Non Solder-resist Mask Defined (NSMD) pad type is recommended over the Solder-resist Mask Defined (SMD) pad type, as it implements the solder resist mask opening 50 m larger per side than the corresponding copper pad. The recommended thickness of the stencil for the soldering paste is 150 m, according to application production process requirements.

DC supply must provide a nominal voltage at VCC pin within the operating range limits. DC supply must be capable of supporting the highest peak / pulse current consumption values and the maximum averaged current consumption values in connected mode, as specified in the SARA-R5 series data sheet [1]. VCC voltage supply should be clean, with very low ripple/noise: provide the suggested bypass capacitors, in particular if the application device integrates an internal antenna. Do not apply loads which might exceed the limit for maximum available current from V_INT supply. Check that voltage level of any connected pin does not exceed the relative operating range. Provide accessible test points directly connected to the following pins of the SARA-R5 series modules: V_INT, PWR_ON and RESET_N for diagnostic purposes. Capacitance and series resistance must be limited on each SIM signal to match the SIM specifications. Insert the suggested pF capacitors on each SIM signal and low capacitance ESD protections if accessible. Check UART signals direction, as the modules signal names follow the ITU-T V.24 recommendation [5]. Use transistors with at least an integrated resistor in the base pin or otherwise put a 10 k resistor on the board in series to the GPIO when those are used to drive LEDs. It is recommended to provide accessible test points directly connected to the UART and USB interface pins (see sections 2.6.1, 2.6.2). Provide adequate precautions for EMC / ESD immunity as required on the application board. Do not apply voltage to any generic digital interface pin of SARA-R5 series modules before the switch-on of the generic digital interface supply source (V_INT). All unused pins can be left unconnected. UBX-19041356 - R03 Confidential Design-in Page 89 of 123 SARA-R5 series - System integration manual 2.13.2 Layout checklist The following are the most important points for a simple layout check:
Check 50 nominal characteristic impedance of the RF transmission line connected to the ANT port (cellular antenna RF interface). Check cellular antenna trace design for regulatory compliance perspective (see section 4.2.3 for FCC United States, section 4.3.2 for ISED Canada, and related section 2.4.2.3) For SARA-R510M8S, check 50 nominal characteristic impedance of the RF transmission line connected to the ANT_GNSS port (GNSS antenna RF interface). Ensure no coupling occurs between the RF interfaces and noisy or sensitive signals (like SIM signals and high-speed digital lines). Optimize placement for minimum length of RF lines. Check the footprint and paste mask designed for SARA-R5 series module as illustrated in section 2.11. lines / parts. VCC line should be enough wide and as short as possible. Route VCC supply line away from RF lines / parts (refer to Figure 27) and other sensitive analog The VCC bypass capacitors in the picoFarad range should be placed as close as possible to the VCC pins, in particular if the application device integrates an internal antenna. Ensure an optimal grounding connecting each GND pin with application board solid ground layer. Use as many vias as possible to connect the ground planes on multilayer application board, providing a dense line of vias at the edges of each ground area, in particular along RF and high speed lines. Keep routing short and minimize parasitic capacitance on the SIM lines to preserve signal integrity. USB_D+ / USB_D- traces should meet the characteristic impedance requirement (90 differential and 30 common mode) and should not be routed close to any RF line / part. 2.13.3 Antennas checklist Antenna termination should provide 50 characteristic impedance with V.S.W.R at least less than 3:1 (recommended 2:1) on operating bands in deployment geographical area. Follow the recommendations of the antenna producer for correct antenna installation and deployment (PCB layout and matching circuitry). Ensure compliance with any regulatory agency RF radiation requirement, as reported in section 4.2.2 for FCC United States, in section 4.3.1 for ISED Canada, and in section 4.4 for RED Europe. Ensure high isolation between the cellular antenna and any other antennas or transmitters For SARA-R510M8S, ensure high isolation between the cellular antenna and the GNSS antenna present on the end device.
(see also section 1.7.4) UBX-19041356 - R03 Confidential Design-in Page 90 of 123 SARA-R5 series - System integration manual 3 Handling and soldering No natural rubbers, no hygroscopic materials or materials containing asbestos are employed. 3.1 Packaging, shipping, storage and moisture preconditioning For information pertaining to SARA-R5 series reels / tapes, Moisture Sensitivity levels (MSD), shipment and storage information, as well as drying for preconditioning, see the SARA-R5 series data sheet [1] and the u-blox package information user guide [15]. 3.2 Handling The SARA-R5 series modules are Electro-Static Discharge (ESD) sensitive devices. Ensure ESD precautions are implemented during handling of the module. Electro-Static Discharge (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials caused by direct contact or induced by an electrostatic field. The term is usually used in the electronics and other industries to describe momentary unwanted currents that may cause damage to electronic equipment. The ESD sensitivity for each pin of SARA-R5 series modules (as Human Body Model according to JESD22-A114F) is specified in the SARA-R5 series data sheet [1]. ESD prevention is based on establishing an Electrostatic Protective Area (EPA). The EPA can be a small working station or a large manufacturing area. The main principle of an EPA is that there are no highly charging materials near ESD sensitive electronics, all conductive materials are grounded, workers are grounded, and charge build-up on ESD sensitive electronics is prevented. International standards are used to define typical EPA and can be obtained for example from the International Electrotechnical Commission (IEC) or the American National Standards Institute (ANSI). In addition to standard ESD safety practices, the following measures should be taken into account whenever handling the SARA-R5 series modules:
Unless there is a galvanic coupling between the local GND (i.e. the work table) and the PCB GND, then the first point of contact when handling the PCB must always be between the local GND and PCB GND. Before mounting an antenna patch, connect the ground of the device. When handling the module, do not come into contact with any charged capacitors and be careful when contacting materials that can develop charges (e.g. patch antenna, coax cable, soldering iron). To prevent electrostatic discharge through the RF pin, do not touch any exposed antenna area. If there is any risk that such exposed antenna area is touched in a non-ESD protected work area, implement adequate ESD protection measures in the design. When soldering the module and patch antennas to the RF pin, make sure to use an ESD-safe soldering iron. UBX-19041356 - R03 Confidential Handling and soldering Page 91 of 123 SARA-R5 series - System integration manual 3.3 Soldering 3.3.1 Soldering paste
"No Clean" soldering paste is strongly recommended for SARA-R5 series modules, as it does not require cleaning after the soldering process has taken place. The paste listed in the example below meets these criteria. Soldering paste:
Alloy specification:
Melting temperature:
Stencil thickness:
OM338 SAC405 / Nr.143714 (Cookson Electronics) 95.5% Sn / 3.9% Ag / 0.6% Cu (95.5% tin / 3.9% silver / 0.6% copper) 95.5% Sn / 4.0% Ag / 0.5% Cu (95.5% tin / 4.0% silver / 0.5% copper) 217 C 150 m for base boards The final choice of the soldering paste depends on the approved manufacturing procedures. The paste-mask geometry for applying soldering paste should meet the recommendations in section 2.11. The quality of the solder joints should meet the appropriate IPC specification. 3.3.2 Reflow soldering A convection type-soldering oven is strongly recommended for SARA-R5 series modules over the infrared type radiation oven. Convection heated ovens allow precise control of the temperature and all parts will be heated up evenly, regardless of material properties, thickness of components and surface color. Consider the IPC-7530A Guidelines for temperature profiling for mass soldering (reflow and wave) processes. Reflow profiles are to be selected according to the following recommendations. Failure to observe these recommendations can result in severe damage to the device!
Preheat phase Initial heating of component leads and balls. Residual humidity will be dried out. Note that this preheat phase will not replace prior baking procedures. Temperature rise rate: max 3 C/s Time: 60 120 s End temperature: +150 +200 C Heating/ reflow phase If the temperature rise is too rapid in the preheat phase it may cause excessive slumping. If the preheat is insufficient, rather large solder balls tend to be generated. Conversely, if performed excessively, fine balls and large balls will be generated in clusters. If the temperature is too low, non-melting tends to be caused in areas containing large heat capacity. The temperature rises above the liquidus temperature of +217 C. Avoid a sudden rise in temperature as the slump of the paste could become worse. Limit time above +217 C liquidus temperature: 40 60 s Peak reflow temperature: +245 C UBX-19041356 - R03 Confidential Handling and soldering Page 92 of 123 SARA-R5 series - System integration manual Cooling phase A controlled cooling avoids negative metallurgical effects of the solder (solder becomes more brittle) and possible mechanical tensions in the products. Controlled cooling helps to achieve bright solder fillets with a good shape and low contact angle. Temperature fall rate: max 4 C/s To avoid falling off, modules should be placed on the topside of the motherboard during soldering. The soldering temperature profile chosen at the factory depends on additional external factors like choice of soldering paste, size, thickness and properties of the base board, etc. Exceeding the maximum soldering temperature and the maximum liquidus time limit in the recommended soldering profile may permanently damage the module. Figure 69: Recommended soldering profile The modules must not be soldered with a damp heat process. 3.3.3 Optical inspection 3.3.4 Cleaning After soldering the module, inspect it optically to verify that it is correctly aligned and centered. Cleaning the modules is not recommended. Residues underneath the modules cannot be easily removed with a washing process. Cleaning with water will lead to capillary effects where water is absorbed in the gap between the baseboard and the module. The combination of residues of soldering flux and encapsulated water leads to short circuits or resistor-like interconnections between neighboring pads. Water will also damage the sticker and the ink-jet printed text. Cleaning with alcohol or other organic solvents can result in soldering flux residues flooding into the housing, area that is not accessible for post-wash inspections. The solvent will also damage the sticker and the ink-jet printed text. Ultrasonic cleaning will permanently damage the module, in particular the quartz oscillators. For best results, use a "no clean" soldering paste and eliminate the cleaning step after the soldering. UBX-19041356 - R03 Confidential Handling and soldering Page 93 of 123

SARA-R5 series - System integration manual 3.3.5 Repeated reflow soldering Repeated reflow soldering processes and soldering the module upside-down are not recommended. Boards with components on both sides may require two reflow cycles. In this case, the module should always be placed on the side of the board that is submitted into the last reflow cycle. The reason for this (besides others) is the risk of the module falling off due to the significantly higher weight in relation to other components. u-blox gives no warranty against damages to the SARA-R5 series modules caused by performing more than a total of two reflow soldering processes (one reflow soldering process to mount the SARA-R5 series module, plus one reflow soldering process to mount other parts). 3.3.6 Wave soldering SARA-R5 series LGA modules must not be soldered with a wave soldering process. Boards with combined through-hole technology (THT) components and surface-mount technology
(SMT) devices require wave soldering to solder the THT components. No more than one wave soldering process is allowed for a board with a SARA-R5 series module already populated on it. Performing a wave soldering process on the module can result in severe damage to the device!
u-blox gives no warranty for damages to the SARA-R5 series modules caused by performing more than a total of two soldering processes (one reflow soldering process to mount the SARA-R5 series module, plus one wave soldering process to mount other THT parts on the application board). 3.3.7 Hand soldering Hand soldering is not recommended. 3.3.8 Rework Rework is not recommended. immediately terminate the warranty. 3.3.9 Conformal coating Never attempt a rework on the module itself, e.g. replacing individual components. Such actions Certain applications employ a conformal coating of the PCB using HumiSeal or other related coating products. These materials affect the RF properties of the cellular modules and it is important to prevent them from flowing into the module. The RF shields do not provide 100% protection for the module from coating liquids with low viscosity, therefore care is required in applying the coating. Conformal Coating of the module will void the warranty. 3.3.10 Casting If casting is required, use viscose or another type of silicon pottant. The OEM is strongly advised to qualify such processes in combination with the cellular modules before implementing this in production. Casting will void the warranty.

The numerous ground pins should be sufficient to provide optimum immunity to interference and noise. u-blox gives no warranty for damages to the cellular modules caused by soldering metal cables or any other forms of metal strips directly onto the EMI covers. 3.3.12 Use of ultrasonic processes The cellular modules contain components which are sensitive to ultrasonic waves. Use of any ultrasonic processes (cleaning, welding etc.) may cause damage to the module. u-blox gives no warranty for damages to the cellular modules caused by any ultrasonic processes.

Regulatory certifications o Country-specific approval required by local government in most regions and countries, as:
CE (European Conformity) marking for European Union FCC (Federal Communications Commission) approval for the United States Industry certifications o Telecom industry-specific approval verifying interoperability between devices and networks:
GCF (Global Certification Forum) PTCRB (PCS Type Certification Review Board) Operator certifications o Operator-specific approvals required by some mobile network operator, such as:
AT&T network operator in United States Verizon Wireless network operator in United States The manufacturer of the end-device that integrates a SARA-R5 series module must take care of all certification approvals required by the specific integrating device to be deployed in the market. The required certification scheme approvals and relative testing specifications applicable to the end-device that integrates a SARA-R5 series module differ depending on the country or the region where the integrating device is intended to be deployed, on the relative vertical market of the device, on type, features and functionalities of the whole application device, and on the network operators where the device is intended to operate. Table 39 summarizes the main approvals planned for SARA-R5 series modules.

UBX-19041356 - R03 Confidential Approvals Page 96 of 123 SARA-R5 series - System integration manual The SARA-R5 series modules include the capability to configure the device by selecting the operating Mobile Network Operator Profile, Radio Access Technology, and bands. In the SARA-R5 series AT commands manual [2], see the +UMNOPROF, +URAT, and +UBANDMASK AT commands. As these configuration decisions are made, u-blox reminds manufacturers of the host application device integrating the SARA-R5 series modules to take care of compliance with all the certification approvals requirements applicable to the specific integrating device to be deployed in the market. It is strongly recommended to configure the module to the applicable MNO profile, RAT, and LTE bands intended for the host end-device and within regulatory compliance. The certification of the host application device that integrates a SARA-R5 series module and the compliance of the host application device with all the applicable certification schemes, directives and standards are the sole responsibility of the host application device manufacturer. SARA-R5 series modules are certified according to all capabilities and options stated in the Protocol Implementation Conformance Statement document (PICS) of the module. The PICS, according to the 3GPP TS 36.521-2 [12] and 3GPP TS 36.523-2 [13], is a statement of the implemented and supported capabilities and options of a device. The PICS document of the host device integrating SARA-R5 series modules must be updated from the module PICS statement if any feature stated as supported by the module in its PICS document is not implemented or disabled in the host application device. For more details regarding the AT commands settings that affect the PICS, see the SARA-R5 series AT commands manual [2]. Check the specific settings required by the mobile network operators in use by the host application device, as they may differ from the AT commands factory-programmed settings of the module. 4.2 US Federal Communications Commission notice United States Federal Communications Commission (FCC) ID: XPYUBX19KM01 4.2.1 Safety warnings review the structure Equipment for building-in.

UBX-19041356 - R03 Confidential Approvals Page 101 of 123 SARA-R5 series - System integration manual 5 Product testing 5.1 u-blox in-series production test u-blox focuses on high quality for its products. All units produced are fully tested automatically on the production line. Stringent quality control processes have been implemented in the production line. Defective units are analyzed in detail to improve production quality. This is achieved with automatic test equipment (ATE) in the production line, which logs all production and measurement data. A detailed test report for each unit can be generated from the system. The following Figure 70 illustrates the typical automatic test equipment (ATE) in a production line. The following typical tests are among the production tests. Digital self-test (firmware download, flash firmware verification, IMEI programming) Measurement of voltages and currents Adjustment of ADC measurement interfaces Functional tests (serial interface communication, SIM card communication) Digital tests (GPIOs and other interfaces) Measurement and calibration of RF characteristics in all supported bands (such as receiver S/N verification, frequency tuning of the reference clock, calibration of transmitter and receiver power levels, etc.) Verification of the RF characteristics after calibration (i.e. modulation accuracy, power levels, spectrum, etc. are checked to ensure they are all within tolerances when calibration parameters are applied) Figure 70: Automatic test equipment for module tests UBX-19041356 - R03 Confidential Product testing Page 102 of 123 SARA-R5 series - System integration manual 5.2 Test parameters for OEM manufacturers Because of the testing done by u-blox (with 100% coverage), an OEM manufacturer does not need to repeat the firmware tests or measurements of the module RF performance or tests over analog and digital interfaces in their production test. However, an OEM manufacturer should focus on:
Module assembly on the device; it should be verified that:
o The soldering and handling process did not damage the module components o All module pins are well soldered on the device board o There are no short circuits between pins Component assembly on the device; it should be verified that:
o Communication with the host controller can be established o The interfaces between the module and device are working o Overall RF functional test of the device including the antenna/s Dedicated tests can be implemented to check the device. For example, the measurement of the module current consumption when set in a specified status can detect a short circuit if compared with a Golden Device result. In addition, module AT commands can be used to perform functional tests on the digital interfaces
(communication with the host controller, check the SIM interface, GPIOs, etc.) or to perform RF functional tests (see the following section 5.2.2 for details). 5.2.1 Go / No go tests for integrated devices A Go / No go test is typically used to compare the signal quality with a Golden Device. The cellular RF functionality should be checked with the DUT (Device Under Test) placed in a location with excellent cellular network coverage and known cellular signal quality. This test should be performed after the data connection has been established. +CSQ is the typical AT command used to check signal quality in term of RSSI, comparing the DUT with a Golden Device. See the SARA-R5 series AT commands manual [2] for detail usage of the AT command. These kinds of test may be useful as a go / no go test but not for cellular RF performance measurements neither for certifications purpose. This test is suitable also to check the communications with the host controller, the SIM card and the power supply. It is also a mean to verify if components at the cellular RF interface are well soldered. The GNSS RF functionality should be checked with the device under test (DUT) placed in an outdoor position, with excellent sky view (HDOP < 3.0). Let the receiver acquire satellites and compare the signal strength with a Golden Device. As the electro-magnetic field of a redistribution antenna is not homogenous, indoor tests are in most cases not reliable to check the GNSS RF functionality. These kind of tests may be useful as a go/no go test but not for GNSS sensitivity measurements. UBX-19041356 - R03 Confidential Product testing Page 103 of 123 SARA-R5 series - System integration manual 5.2.2 Cellular RF functional tests The overall cellular RF functional test of the device including the antenna can be performed with basic instruments such as a spectrum analyzer (or an RF power meter) and a signal generator with the assistance of the +UTEST AT command over the AT command user interface. The +UTEST AT command provides a simple interface to set the module to Rx or Tx test modes ignoring the LTE signaling protocol. The command can set the module into:
transmitting mode in a specified channel and power level in all supported bands receiving mode in a specified channel to return the measured power level in all supported bands See the SARA-R5 series AT commands manual [2] for the +UTEST AT command syntax description and detail guide of usage. This feature allows the measurement of the transmitter and receiver power levels to check the component assembly related to the module cellular antenna interface and to check other device interfaces on which the RF performance depends. To avoid module damage during a transmitter test, a suitable antenna according to module specifications or a 50 termination must be connected to the ANT port. To avoid module damage during a receiver test, the maximum power level received at the ANT port must meet module specifications. The +UTEST AT command sets the module to emit RF power ignoring LTE signaling protocol. This emission can generate interference that can be prohibited by law in some countries. The use of this feature is intended for testing purposes in controlled environments by qualified users and must not be used during the normal module operation. Follow the instructions suggested in the u-blox documentation. u-blox assumes no responsibilities for the inappropriate use of this feature. Figure 71 illustrates a typical test setup for such an RF functional test.

Spirent GSS6300 Spirent Communications Positioning Technology www.positioningtechnology.co.uk Guidelines for GNSS RF functionality tests:
1. Connect a Multi-GNSS generator to the OEM product. 2. Choose the power level in a way that the Golden Device would report a C/No ratio of 38-40 dBHz. 3. Power up the DUT (Device Under Test) and allow enough time for the acquisition. 4. Read the C/No value from the NMEA GSV or the UBX-NAV-SVINFO message (e.g. with u-center). 5. Compare the results to a Golden Device.

With the u-blox nested design solution, any TOBY, LISA, LARA or SARA module can be alternatively mounted on the same space of a single nested application board as described in Figure 73. Guidelines to implement a nested application board, description of the u-blox reference nested design and comparison between TOBY, LISA, LARA and SARA modules are provided in the nested design application note [21]. TOBY-L2 Figure 73: Cellular modules layout compatibility: all modules can be mounted on the same nested footprint Table 40 summarizes the main interfaces provided by SARA modules:

The different mounting options for the external parts are highlighted in different colors as described in the legend, according to the interfaces supported by the each module, and related characteristics. In the simple schematic diagram shown in Figure 75, the VCC supply of the SARA modules is provided by a suitable supply source, at 3.6 V nominal voltage, not illustrated in the diagram. The application processor controls the VCC supply of the modules by means of a high-side switch. Proper bypass capacitors and EMI filter parts are placed close to the VCC input pins of the modules. While selecting the supply source for SARA cellular modules, consider with adequate safe design margin the maximum current consumption of each SARA cellular module (see the related data sheet
[1], [16], [17], [18], [22], [23], [24]), as it reflects the RATs supported. For additional specific design guidelines, see the VCC interface sections in related system integration manual [19], [20], [25], [26]. The switch-on sequence of SARA-N2, SARA-R500S, SARA-R510M8S, SARA-G3 and SARA-U2 starts by applying a valid VCC supply. Instead, SARA-N3, SARA-R4, SARA-R510S and SARA-G4 modules continue to be switched off even after a valid VCC supply has been applied: the PWR_ON / PWR_CTRL line has to be properly toggled, with valid VCC supply present, to start the switch-on sequence of these modules. The application processor is connected to the SARA modules over main UART interface in the simple schematic diagram illustrated in Figure 75. The design is implemented with the UART interface configured at the same voltage level on both sides
(application processor and SARA module), without using voltage translators, as it is recommended in order to minimize any possible leakage and benefit from the extremely low current consumption of the u-blox LPWA modules, in particular in deep-sleep power saving mode. Thus, the supply level of the application processor is selected to properly set its UART voltage level:
at the VCC level of the module (3.6 V nominal), in case of SARA-N2 at the V_INT level of the module (2.8 V nominal, with VSEL unconnected), in case of SARA-N3 at the V_INT level of the module (3.0 V nominal, with VSEL unconnected), in case of SARA-G4 at the V_INT level of the module (1.8 V nominal), for all the other SARA modules The TXD and RXD data lines, supported by all the SARA modules for AT and data communication, are directly connected with the application processors. For additional specific design guidelines, see the UART sections in the related system integration manual [19], [20], [25], [26]. The RTS, CTS and RI lines are connected with the application processors by 0 jumpers for all the SARA modules except the SARA-N2 series, which does not support hardware flow control functionality and instead supports RI functionality over the CTS output pin. The other UART lines are not implemented in the simple example of design shown in Figure 75, and the DTR input is grounded as required to have URCs and the greeting text sent by SARA-R4, SARA-R5 and SARA-U2 modules. The application processor controls the PWR_ON / PWR_CTRL line by means of an open drain driver in the circuit illustrated in Figure 75, with an external pull-up to V_BCKP for SARA-G3 and SARA-U2 modules. The whole circuit need not be populated for SARA-N2 modules, which do not provide PWR_ON / PWR_CTRL input. UBX-19041356 - R03 Confidential Appendix Page 115 of 123 SARA-R5 series - System integration manual The application processor controls the RESET_N / PWR_OFF line by means of open drain driver too. The assertion or toggling of this line causes different actions:
the RESET_N line triggers an unconditional reboot of the module when toggled, without internal PMU shutdown when set low, in case of SARA-N2, SARA-R5 and SARA-G3 the RESET_N line triggers an unconditional reboot of the module when toggled, with internal PMU shutdown when set low, in case of SARA-N3 and SARA-U2 the RESET_N / PWR_OFF line triggers an unconditional shutdown of the module when set low or toggled, in case of SARA-R4 and SARA-G4 The circuit need not be populated for SARA-R42x modules, not providing RESET_N / PWR_OFF input. The timings for proper control of the PWR_ON / PWR_CTRL, RESET_N / PWR_OFF lines of the SARA modules are reported in the related data sheet [1], [16], [17], [18], [22], [23], [24]. The ANT cellular antenna circuit is implemented in Figure 75 with also the optional ANT_DET antenna detection circuit according to the design guidelines provided in the Antenna interface sections of the related system integration manual [19], [20], [25], [26]. While selecting the antenna for SARA cellular modules, consider the frequency range supported by each SARA module, as illustrated in Figure 74. Designers have to take care of the antenna from all perspective at the very start of the design phase, when the physical dimensions of the application board are under analysis/decision, since the RF compliance of the end-device integrating cellular modules with all the applicable required certification schemes depending on the antennas radiating performance. While implementing the RF antenna design for SARA cellular modules, consider providing the best possible return loss in the frequency range supported by the modules, and place the antenna far from VCC supply line and related parts, as well as far from any possible noise source. The ANT_GNSS circuit is implemented in Figure 75 for SARA-R422M8S and SARA-R510M8S, with also the optional external SAW and LNA for best performance and improved jamming immunity The SIM interface circuit is implemented in Figure 75 with also the optional SIM detection function, according to the design guidelines provided in SIM interface sections of the related system integration manual [19], [20], [25], [26]: bypass capacitors with proper self-resonant frequency are recommended to be placed close to the SIM connector, as well as ESD protections. The GPIO1 that controls a LED as shown in Figure 75, to provide the network status indication, is supported by all SARA modules except SARA-N2 series that can provide this function on the CTS pin. Other functions can be enabled on the GPIOs of the SARA modules, as described in the related data sheet [1], [16], [17], [18], [22], [23], [24], and related AT commands manual [2], [27], [28], [29]. Test-points for diagnostic or FW upgrade are provided as recommended in Figure 75 at these pins:

Choose the right size (see the information in the chapter Bracelet [ 4.2). These values are purely indicative. The best way to know if the Bracelet is not too tight, is to ask the wearer to place his little finger between the leg and the Bracelet. If the finger does not fit, the Bracelet is too tight. The wearer is the only one to know if the Bracelet fits or not. If he does not feel comfortable, another size should be used. Of course, the Bracelet needs to be tight enough to be unremovable as long as it is closed. XS = 240 mm / 9,45 " | S = 270 mm / 10,63 " | M = 300 mm / 11,81 " | L = 320 mm / 12,6 "

Request for Modular/Limited Modular Approval Date: July 15, 2020 Subject: Manufacturers Declaration for - Modular Approval Confidentiality Request for: XPYUBX19KM01
- Limited Modular Approval - Limited Split Modular Approval
- Split Modular Approval 8 Basic Requirements FCC Part 15.212(a)(1) For Items Marked NO(*), the Limited Module Description Must be Filled Out on the Following Pages Modular Approval Requirement Requirement Met 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with FCC limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 15.212(a)(1)(i) Details: <example The module contains a metal shield which covers all RF components and circuitry. The shield is located on the top of the board next to antenna connector>
- YES - NO(*) 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with FCC requirements under conditions of excessive data rates or over-modulation. 15.212(a)(1)(ii) Details: <example Data to the modulation circuit is buffered as described in the operational description provided with the application>
- YES - NO(*) 3. The modular transmitter must have its own power supply regulation on the module. This is intended to ensure that the module will comply with FCC requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. 15.212(a)(1)(iii) Details: <example The module contains its own power supply regulation. Please refer to schematic filed with this application>
- YES - NO(*) 4. The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b), 15.204(c), 15.212(a), and 2.929(b). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph 15.212(b). 15.212(a)(1)(iv) Details: <example The module connects to its antenna using an UFL connector which is considered a non-standard connector. A list of antennas tested and approved with this device may be found in users manual provided with the application>
- YES - NO(*) 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). 15.212(a)(1)(v) Details: <example The module was tested stand-alone as shown in test setup photographs filed with this application>
- YES - NO(*) 070920-02b 6. The modular transmitter must be labeled with its own FCC ID number, or use an electron display (see Modular Approval Requirement Requirement Met KDB Publication 784748). If using a permanently affixed label with its own FCC ID number, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID: XYZMODEL1 or Contains FCC ID:
XYZMODEL1. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains FCC certified transmitter module(s). Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. 15.212(a)(1)(vi) Details: <example There is a label on the module as shown in the labeling exhibit filed with this application. Host specific labeling instructions are shown in the installation manual .filed with this application.>
- YES - NO(*) 7. The modular transmitter must comply with all specific rule or operating requirements applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. 15.212(a)(1)(vii) Details: <example The module complies with FCC Part 15C requirements. Instructions to the OEM installer are provided in the installation manual filed with this application.>
- YES - NO(*) 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. 15.212(a)(1)(viii) Details: <example The module meets Portable exclusion levels as shown in the RF exposure information filed with this application.>
- YES - NO(*) 070920-02b Limited Module Description When Applicable
