This module must not transmit simultaneously with any other antenna or transmitter 6. The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is required to satisfy the SAR requirements of FCC Part 2.1093 If the device is used for other equipment that separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. For this device, OEM integrators must be provided with labeling instructions of finished products. Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:

A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label, the module must be labeled with an FCC ID - Section 2.926 (see 2.2 Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining to the OEM the labeling requirements, options and OEM user manual instructions that are required (see next paragraph). For a host using a certified modular with a standard fixed label, if (1) the modules FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible;

then an additional permanent label referring to the enclosed module: Contains Transmitter Module FCC ID: XMR2021BG950AGL or Contains FCC ID: XMR2021BG950AGL must be used.

Evaluation Board To help customers to develop applications with the module conveniently, Quectel supplies an evaluation board (EVB), USB to RS-232 converter cables, USB data cables, earphone, antennas, and other peripherals to control or to test the module. For more details, refer to document [1]. BG950A-GL&BG951A-GL_Hardware_Design 26 /89 LPWA Module Series 3 Operating Characteristics 3.1. Operating Modes The table below outlines operating modes of the module. Table 7: Overview of Operating Modes Mode Details Normal Operation Idle Talk/Data Software is active. The module has registered on network, and it is ready to send and receive data. Network is connected. decided by network setting and data transfer rate. In this mode, the power consumption is Extended Idle Mode DRX (e-I-DRX) The module and the network may negotiate over non-access stratum signaling the use of e-I-DRX for reducing power consumption, while being available for mobile terminating data and/or network originated procedures within a certain delay dependent on the DRX cycle value. Airplane Mode AT+CFUN=4 or W_DISABLE#* pin can set the module into airplane mode where the RF function is invalid. Minimum Functionality Mode the module into a minimum functionality mode without AT+CFUN=0 can set removing the power supply. In this mode, both RF function and (U)SIM card are invalid. Sleep Mode*

Power OFF Mode The module remains the ability to receive paging message, SMS* and TCP/UDP data from the network normally. In this mode, the current consumption is reduced to a low level. The modules power supply is shut down by its power management unit. In this interfaces are inaccessible, while the mode, the software is inactive, the serial operating voltage (connected to VBAT_BB and VBAT_RF) remains applied. Power Saving Mode

(PSM)*

PSM is similar to power-off, but the module remains registered on the network and there is no need to re-attach or re-establish PDN connections. The current consumption is reduced to a minimized level. BG950A-GL&BG951A-GL_Hardware_Design 27 /89 LPWA Module Series NOTE During e-I-DRX, it is recommended to use UART interface for data communication, as the use of USB interface will increase power consumption. 3.2. Sleep Mode*

BG950A-GL & BG951A-GL can reduce their current consumption to a lower value during the sleep mode. The following sub-chapters describe the power saving procedure of BG950A-GL & BG951A-GL. 3.2.1. UART Application Scenario If the host communicates with the module via UART interface, the following preconditions can let the module enter sleep mode:

Execute AT+QSCLK=2 to enable sleep mode. Drive MAIN_DTR high. Pull the PON_TRIG pin low. The figure illustrates the connection between the module and the host. Figure 3: Sleep Mode Application via UART Interface Driving the module's MAIN_DTR low will wake up the module. When the module has a URC to report, MAIN_RI* signal will wake up the host. See Chapter 4.6.4 for details about MAIN_RI* behavior. AP_READY* will detect the sleep state of the host (can be configured to high voltage level or low voltage level detection). See AT+QCFG="apready" in document [2] for details. BG950A-GL&BG951A-GL_Hardware_Design 28 /89 LPWA Module Series 3.3. Power Saving Mode (PSM)*

BG950A-GL & BG951A-GL module can enter PSM for reducing its power consumption. The mode is similar to power-off, but the module remains registered on the network and there is no need to re-attach or re-establish PDN connections. So BG950A-GL & BG951A-GL module in PSM cannot immediately respond users requests. When the module wants to use the PSM, it shall request an Active Time value during every Attach and TAU procedures. If the network supports PSM and accepts that the module uses PSM, it will confirm the usage of PSM by allocating an Active Time value to the module. If the module wants to change the Active Time value, e.g. when the conditions are changed in the module, the module consequently requests the value it wants in the TAU procedure. If PSM is supported by the network, then it can be enabled via AT+CPSMS*. Either of the following methods will wake up the module from PSM:

Drive PWRKEY low will wake up the module. When the T3412_EXT timer expires, the module will be automatically woken up. When PON_TRIG is pulled high and maintains its level statue, the module will wake up from PSM

(Power Saving Mode). PON_TRIG is pulled down by default. NOTE See document [3] for details about AT+CPSMS*. 3.4. Extended Idle Mode DRX (e-I-DRX) The module (UE) and the network may negotiate over non-access stratum signalling the use of e-I-DRX for reducing its power consumption, while being available for mobile terminating data and/or network originated procedures within a certain delay dependent on the DRX cycle value. Applications that want to use e-I-DRX need to consider specific handling of mobile terminating services or data transfers, and in particular, they need to consider the delay tolerance of mobile terminated data. In order to negotiate the use of e-I-DRX, the UE requests e-I-DRX parameters during attach procedure and RAU/TAU procedure. The EPC may reject or accept the UE request for enabling e-I-DRX. In case the EPC accepts e-I-DRX, the EPC based on operator policies and, if available, the e-I-DRX cycle length value in the subscription data from the HSS, may also provide different values of the e-I-DRX parameters than what was requested by the UE. If the EPC accepts the use of e-I-DRX, the UE applies e-I-DRX based on the received e-I-DRX parameters. If the UE does not receive e-I-DRX parameters in the BG950A-GL&BG951A-GL_Hardware_Design 29 /89 relevant accept message because the EPC rejected its request or because the request was received by EPC not supporting e-I-DRX, the UE shall apply its regular discontinuous reception. If e-I-DRX is supported by the network, then it can be enabled by AT+CEDRXS=1. LPWA Module Series NOTE See document [3] for details about AT+CEDRXS. 3.5. Airplane Mode When the module enters airplane mode, correlative with RF function will be inaccessible. This mode can be set via the following ways. the RF function will be disabled, and all AT commands Hardware:

W_DISABLE#* pin is pulled up by default. Driving it low will let the module enter airplane mode. Software:

AT+CFUN=<fun> provides choices of the functionality level through setting <fun> into 0, 1 or 4. AT+CFUN=0: Minimum functionality (Both RF function and (U)SIM function are disabled). AT+CFUN=1: Full functionality (by default). AT+CFUN=4: Airplane mode (RF function is disabled). NOTE 1. Airplane mode control via W_DISABLE#* is disabled in firmware by default. It can be enabled by AT+QCFG="airplanecontrol"*. More details about the command will be provided in document [2]. 2. The execution of AT+CFUN will not affect GNSS function. BG950A-GL&BG951A-GL_Hardware_Design 30 /89 For every VBAT transition/re-insertion from 0 V, VBAT slew rate < 25 mV/s. After the module starts up normally, in order to ensure full-function mode, the minimum power supply voltage should be higher than 2.2 V. LPWA Module Series 3.6. Power Supply 3.6.1.

For more details, see document [3]. 3.6.3. Requirements for Voltage Stability The power supply range of the module is from 2.2 V to 4.5 V. Make sure the input voltage will never drop below 2.2 V. BG950A-GL&BG951A-GL_Hardware_Design 31 /89 LPWA Module Series Figure 4: Power Supply Limits During Burst Transmission To decrease voltage s drop, a bypass capacitor of about 100 F with low ESR should be used, and a multi-layer ceramic chip (MLCC) capacitor array should also be reserved due to its ultra-low ESR. It is recommended to use three ceramic capacitors for composing the MLCC array (100 nF, 33 pF, 10 pF), and place these capacitors close to VBAT pins. The main power supply from an external application must be a single voltage source and can be expanded to two sub paths with the star structure. The width of VBAT_BB trace should be no less than 1 mm. The width of VBAT_RF trace should be no less than 1 mm. In principle, the longer the VBAT trace is, the wider it will be. In addition, to ensure the stability of the power supply, it is necessary to add two high-power TVSs at the front end of each power supply. Reference circuit of power supply is shown as below:

Table 9: Pin Definition of PWRKEY Pin Name Pin No. I/O Description Comment PWRKEY 15 DI Turn on/off the module Internally pulled up resistor is 470 k. When the module is in power off mode, it can be turned on and enter normal operation mode by driving the PWRKEY low for 5001000 ms. It is recommended to use an open drain/collector driver to control the PWRKEY. Figure 6: Turn on the Module by Using Driving Circuit the PWRKEY is by using a button directly. When pressing the button, an Another way to control electrostatic strike may generate from finger. Therefore, a TVS component shall be placed near the button for ESD protection.

. NOTE Ensure that VBAT is stable for at least 30 ms before pulling down the PWRKEY. 3.8. Turn Off The following procedures can be used to turn off the module:

3.8.1. Turn off the Module with PWRKEY*

When the module is in power on mode, driving the PWRKEY low for at least 6501500 ms, then the module will execute power-down procedure after the PWRKEY is released. BG950A-GL&BG951A-GL_Hardware_Design 34 /89 LPWA Module Series Figure 9: Power-down Timing 3.8.2. Turn off the Module with AT Command It is safe to use AT+QPOWD* to turn off the module, which is equal to turn off the module via PWRKEY pin. Refer to document [3] for details about AT+QPOWD*. NOTE 1. To avoid damaging the internal flash, do not switch off the power supply when the module works normally. Only after the module is turned off by PWRKEY or AT command, the power supply can be cut off. 2. When turning off module with AT command, keep PWRKEY at a high level after the execution of power-off command. Otherwise, the module will be turned on again after turned off. 3.9. Reset The module can be reset by driving the RESET_N low for a certain time (TBD) and then releasing it. The RESET_N signal is sensitive to interference, so it is recommended to route the trace as short as possible and surround it with ground. Table 10: Pin Definition of RESET_N Pin Name Pin No. I/O Description BG950A-GL&BG951A-GL_Hardware_Design 35 /89 LPWA Module Series RESET_N 17 DI Reset the module The recommended circuit is similar to the PWRKEY control circuit.

BG950A-GL & BG951A-GL modules provide one PON_TRIG pin which is used to wake up the module from PSM*. Table 11: Pin Definition of PON_TRIG Pin Name Pin No. I/O Description Comment PON_TRIG 96 DI Wake up the module from PSM 1.8 V power domain. A reference circuit is shown in the following figure. BG950A-GL&BG951A-GL_Hardware_Design 37 /89 LPWA Module Series Figure 13: Reference Circuit of PON_TRIG NOTE 1. VDD_1V8 is provided by an external LDO. 2. The PON_TRIG pin is pulled down by default. After the module starts up, the PON_TRIG pin must be the the main UART interface can communicate. In normal operation mode, pulled up so that PON_TRIG pin is recommended to be pulled up all the time. 3. After sending the AT command that makes the module enter PSM mode, drive PON_TRIG low can let the module enter PSM mode. When you need to wake up the module from PSM mode, PON_TRIG should be pulled up all the time, otherwise the module will re-enter PSM mode. 4. Send AT+QSCLK first, and then drive PON_TRIG low after pulling down MAIN_DTR can make the module enter sleep mode, otherwise the module cannot enter sleep mode normally. When you need to wake up the module from sleep mode, PON_TRIG pin also should be pulled up all the time before pulling up MAIN_DTR, otherwise the main UART interface cannot communicate.

Figure 15: Reference Circuit of (U)SIM Interface with a 6-Pin (U)SIM Card Connector BG950A-GL&BG951A-GL_Hardware_Design 40 /89 LPWA Module Series To enhance the reliability and availability of the (U)SIM card in applications, please follow the criteria below in the (U)SIM circuit design:

Keep the placement of (U)SIM card connector as close to the module as possible. Keep the trace length as less than 200 mm as possible. Keep (U)SIM card signals away from RF and VBAT traces. Assure the ground between the module and the (U)SIM card connector short and wide. Keep the trace width of ground and USIM_VDD no less than 0.5 mm to maintain the same electric potential. If the ground is complete on customers PCB, USIM_GND can be connected to PCB ground directly. Make sure the bypass capacitor between USIM_VDD and USIM_GND less than 1 F, and place it as close to (U)SIM card connector as possible. To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away from each other and shield them with surrounded ground. To offer good ESD protection, it is recommended to add a TVS diode array of which parasitic capacitance should not be more than 15 pF. The 0 resistors should be added in series between the module and the (U)SIM card to facilitate debugging. The 33 pF capacitors are used for filtering interference of EGSM900. Please note that the (U)SIM peripheral circuit should be close to the

(U)SIM card connector. The pull-up resistor on USIM_DATA trace can improve anti-jamming capability when long layout trace and sensitive occasions are applied, and should be placed close to the (U)SIM card connector. 4.2. USB Interface*

The module provides one USB interface. The USB interface complies with the USB 2.0 specifications, and supports Full-speed (12 Mbps) and Low-speed (1.5 Mbps) for USB 2.0. USB interface is used AT command communication, data transmission, software debugging and firmware upgrade.

Require differential impedance of 90 . BG950A-GL&BG951A-GL_Hardware_Design 41 /89 It is recommended to reserve test points for debugging and firmware upgrading in customers designs. LPWA Module Series Figure 16: Reference Circuit of USB Application To ensure the integrity of USB data trace signal, resistors R1 and R2 should be placed close to the module, and these resistors should be placed close to each other. The extra stubs of trace must be as short as possible. To meet USB 2.0 specification, comply with the following principles while designing the USB interface. It is important to route the USB signal traces as differential pairs with ground surrounded. The impedance of USB differential trace is 90 . Do not route signal traces under crystals, oscillators, magnetic devices, PCIe and RF signal traces. It is important to route the USB differential traces in inner-layer of the PCB, and surround the traces with ground on that layer and with ground planes above and below. Junction capacitance of the ESD protection device might cause influences on USB data traces, so pay attention to the selection of the device. Typically, the stray capacitance should be less than 2 pF . Keep the ESD protection devices as close to the USB connector as possible. If possible, reserve a 0 resistor on USB_DP and USB_DM traces respectively. For more details about the USB specifications, visit http://www.usb.org/home.

Reference Design of RF Routing BG950A-GL&BG951A-GL_Hardware_Design 59 /89 LPWA Module Series the characteristic impedance of all RF traces should be controlled to 50 . The For users PCB, impedance of the RF traces is usually determined by the trace width (W), the materials dielectric constant, the height from the reference ground to the signal layer (H), and the spacing between RF traces and grounds (S). Microstrip or coplanar waveguide is typically used in RF layout to control characteristic impedance. The following are reference designs of microstrip or coplanar waveguide with different PCB structures. Figure 25: Microstrip Design on a 2-layer PCB Figure 26: Coplanar Waveguide Design on a 2-layer PCB BG950A-GL&BG951A-GL_Hardware_Design 60 /89 Figure 27: Coplanar Waveguide Design on a 4-layer PCB (Layer 3 as Reference Ground) LPWA Module Series Figure 28: Coplanar Waveguide Design on a 4-layer PCB (Layer 4 as Reference Ground) To ensure RF performance and reliability, follow the principles below in RF layout design:

Use an impedance simulation tool to accurately control the characteristic impedance of RF traces to 50 . The GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully connected to ground. The distance between the RF pins and the RF connector should be as short as possible and all the right-angle traces should be changed to curved ones. The recommended trace angle is 135. There should be clearance under the signal pin of the antenna connector or solder joint. The reference ground of RF traces should be complete. Meanwhile, adding some ground vias around RF traces and the reference ground could help to improve RF performance. The distance between the ground vias and RF traces should be no less than two times the width of RF signal traces (2 W). Keep RF traces away from interference sources, and avoid intersection and paralleling between traces on adjacent layers. For more details about RF layout, see document [5]. 5.4.

BG950A-GL&BG951A-GL_Hardware_Design 75 /89 LPWA Module Series 9 Storage, Manufacturing & Packaging 9.1. Storage Conditions The module is provided with vacuum-sealed packaging. MSL of the module is rated as 3. The storage requirements are shown below. 1. Recommended Storage Condition: The temperature should be 23 5 C and the relative humidity should be 3560 %. 2. The storage life (in vacuum-sealed packaging) is 12 months in Recommended Storage Condition. 3. The floor life of the module is 168 hours 20 in a plant where the temperature is 23 5 C and relative humidity is below 60 %. After the vacuum-sealed packaging is removed, the module must be processed in reflow soldering or other high-temperature operations within 168 hours. Otherwise, the module should be stored in an environment where the relative humidity is less than 10 % (e.g. a drying cabinet). 4. The module should be pre-baked to avoid blistering, cracks and inner-layer separation in PCB under the following circumstances:

The module is not stored in Recommended Storage Condition;

Violation of the third requirement above occurs;

Vacuum-sealed packaging is broken, or the packaging has been removed for over 24 hours;

Before module repairing. 5. If needed, the pre-baking should follow the requirements below:

The module should be baked for 8 hours at 120 5 C;

All modules must be soldered to PCB within 24 hours after the baking, otherwise they should be put in a dry environment such as in a drying oven. NOTE 20 This floor life is only applicable when the environment conforms to IPC/JEDEC J-STD-033. It is recommended to start the solder reflow process within 24 hours after the package is removed if the temperature and moisture do not conform to, or are not sure to conform to IPC/JEDEC J-STD-033. And do not remove the packages of tremendous modules if they are not ready for soldering. BG950A-GL&BG951A-GL_Hardware_Design 76 /89 LPWA Module Series 1. To avoid blistering, layer separation and other soldering issues, extended exposure of the module to the air is forbidden. 2. Take out the module from the package and put it on high-temperature-resistant fixtures before baking. All modules must be soldered to PCB within 24 hours after the baking, otherwise put them in the drying oven. If shorter baking time is desired, see IPC/JEDEC J-STD-033 for the baking procedure. 3. Pay attention to ESD protection, such as wearing anti-static gloves, when touching the modules. 9.2. Manufacturing and Soldering Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the stencil openings and then penetrate to the PCB. Apply proper force on the squeegee to produce a clean stencil surface on a single pass. To guarantee module soldering quality, the thickness of stencil for the module is recommended to be 0.130.15 mm. For more details, see document [6]. The peak reflow temperature should be 235246 C, with 246 C as the absolute maximum reflow temperature. To avoid damage to the module caused by repeated heating, it is strongly recommended that the module should be mounted only after reflow soldering for the other side of PCB has been completed. The recommended reflow soldering thermal profile (lead-free reflow soldering) and related parameters are shown below.
