If eSIM is selected, then any external (U)SIM cannot be used. BG95-M5 and BG95-M6 do not support eSIM. 2. PWRKEY output voltage is 1.5 V because of the voltage drop inside the Qualcomm chipset. Due to platform limitations, the chipset has integrated the reset function into PWRKEY. Therefore, never pull down PWRKEY to GND permanently. 3. RESET_N connects directly to PWRKEY inside the module. 4. Do not use ADC0 and ADC1 simultaneously, as ADC1 connects directly to ADC0 inside the module. BG95 supports use of only one ADC interface at a time: either ADC0 or ADC1. 2.4.

For every VBAT transition/re-insertion from 0 V, the minimum power supply voltage should be higher than 2.7 V. After the module starts up normally, the minimum safety voltage is 2.6 V. In order to ensure full-function mode, the minimum power supply voltage should be higher than 2.8 V. 5. PWRKEY output voltage is 1.5 V because of the voltage drop inside the Qualcomm chipset. Due to platform limitations, the chipset has integrated the reset function into PWRKEY. Therefore, never pull down PWRKEY to GND permanently. 6. RESET_N connects directly to PWRKEY inside the module. 7. Do not use ADC0 and ADC1 simultaneously, as ADC1 connects directly to ADC0 inside the module. BG95 series module supports use of only one ADC interface at a time: either ADC0 or ADC1. 8. When PSM is enabled, the function of PSM_IND pin will be activated after the module is rebooted. When PSM_IND is in high voltage level, the module is in normal operation state, when it is in low voltage level, the module is in PSM. 9. GNSS_TXD (pin 27) and GRFC2 (pin 84) are BOOT_CONFIG pins. Never pull them up before startup, otherwise the module cannot power on normally. 10. Keep all RESERVED pins and unused pins open. 11. * means under development. 3.3. Operating Modes The table below briefly summarizes the various operating modes of BG95 series module. BG95_Series_Hardware_Design 34 / 106 LPWA Module Series BG95 Series Hardware Design Table 6: Overview of BG95 Operating Modes Mode Details Normal Operation Extended Idle Mode DRX
(e-I-DRX) Airplane Mode Minimum Functionality Mode Sleep Mode Connected Network has been connected. In this mode, the power consumption may vary with the network setting and data transfer rate. Idle Software is active. The module remains registered on network, and it is ready to send and receive data. BG95 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. AT+CFUN=4 or W_DISABLE#* pin can set the module into airplane mode. In this case, RF function is invalid. AT+CFUN=0 can set the module into a minimum functionality mode without removing the power supply. In this case, both RF function and (U)SIM card are invalid. In this mode, the current consumption of the module is reduced to a lower level. During this mode, the module can still receive paging message, SMS and TCP/UDP data from the network normally. Power OFF Mode In this mode, the power management unit shuts down the power supply. The software is not active. The serial interfaces are not accessible. But the operating voltage
(connected to VBAT_RF and VBAT_BB) remains applied. Power Saving Mode
(PSM) The module may enter PSM to reduce its power consumption. 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. 1. During e-I-DRX, it is recommended to use UART interface for data communication, as the use of USB interface increases power consumption.
* means under development. NOTES 2. 3.4. Power Saving 3.4.1. Airplane Mode When the module enters airplane mode, the RF function does not work, and all AT commands correlative with RF function are inaccessible. This mode can be set via the following ways. BG95_Series_Hardware_Design 35 / 106 LPWA Module Series BG95 Series Hardware Design Hardware:
W_DISABLE#* is pulled up by default. Driving it low makes the module enter airplane mode. Software:
AT+CFUN=<fun> provides choice of the functionality level, through setting <fun> into 0, 1 or 4. AT+CFUN=0: Minimum functionality mode. Both (U)SIM and RF functions are disabled. AT+CFUN=1: Full functionality mode (by default). AT+CFUN=4: Airplane mode. RF function is disabled. NOTES 1. Airplane mode control via W_DISABLE# is disabled in firmware by default. It can be enabled by AT+QCFG="airplanecontrol" command which is still under development. See document [2] for the details about the command. 2. The execution of AT+CFUN command will not affect GNSS function. 3.
* means under development. 3.4.2. Power Saving Mode (PSM) BG95 module can enter PSM to reduce 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 BG95 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 command. Either of the following methods can wake up the module from PSM:
Wake up the module from PSM through a rising edge on PON_TRIG. (Recommended) Wake up the module by driving PWRKEY low. The module is woken up automatically when the T3412_Ext timer expires. NOTE See document [2] for details about AT+CPSMS command. BG95_Series_Hardware_Design 36 / 106 LPWA Module Series BG95 Series Hardware Design 3.4.3. 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 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 command. See document [2] for details about AT+CEDRXS command. NOTE 3.4.4. Sleep Mode 3.4.4.1. UART Application BG95 is able to reduce its current consumption to a lower value during the sleep mode. The following sub-chapters describe the power saving procedure of BG95 series module. If the host communicates with the module via UART interface, the following preconditions can let the module enter sleep mode. Execute AT+QSCLK=1 command to enable sleep mode. Drive MAIN_DTR pin high. The following figure shows the connection between the module and the host. BG95_Series_Hardware_Design 37 / 106 LPWA Module Series BG95 Series Hardware Design Figure 3: Sleep Mode Application via UART When the module has URC to report, MAIN_RI signal wakes up the host. See Chapter 3.15 for details about MAIN_RI behavior. Driving MAIN_DTR low wakes up the module. AP_READY* detects the sleep state of the host (can be configured to high level or low level detection). See AT+QCFG="apready" command in document [2] for details. NOTE
* means under development. 3.5. Power Supply 3.5.1. Power Supply Pins BG95 provides the following four VBAT pins for connection with an external power supply. There are two separate voltage domains for VBAT. Two VBAT_RF pins for modules RF part. Two VBAT_BB pins for modules baseband part. The following table shows the details of VBAT pins and ground pins.

After the module starts up normally, the minimum safety voltage is 2.6 V. In order to ensure full-function mode, the minimum power supply voltage should be higher than 2.8 V. 3.5.2. Decrease Voltage Drop BG95-M1/-M2/-N1: The power supply range of BG95-M1/-M2/-N1 is 2.64.8 V. For every VBAT transition/re-insertion from 0 V, the minimum power supply voltage should be higher than 2.7 V. After the module starts up normally, the minimum safety voltage is 2.6 V. In order to ensure full-function mode, the minimum power supply voltage should be higher than 2.8 V. Ensure the input voltage never drop below 2.6 V. BG95-M3/-M5/-M6: The power supply range of BG95-M3/-M5/-M6 is from 3.34.3 V. Please assure the input voltage will never drop below 3.3 V. BG95-M4: The power supply range of BG95-M4 is from 3.24.2 V. Ensure the input voltage never BG95_Series_Hardware_Design 39 / 106 LPWA Module Series BG95 Series Hardware Design drop below 3.2 V. BG95-MF: The typical power supply of BG95-MF is 3.8 V. The following figure shows the voltage drop during burst transmission in 2G network of BG95-M3/-M5. The voltage drop is less in LTE Cat M1 and/or LTE Cat NB2 networks. Burst Transmission Burst Transmission VBAT Min.3.3V Drop Ripple Figure 4: Power Supply Limits during Burst Transmission (BG95-M3/-M5) To decrease voltage drop, a bypass capacitor of about 100 F with low ESR should be used, and a multi-layer ceramic chip capacitor (MLCC) array should also be reserved due to its low ESR. It is recommended to use three ceramic capacitors (100 nF, 33 pF, 10 pF) for composing the MLCC array, and place these capacitors close to VBAT pins. The main power supply from an external application has to be a single voltage source and can be expanded to two sub paths with star structure. The width of VBAT_BB trace should be no less than 0.6 mm, and the width of VBAT_RF trace should be no less than 2 mm. In principle, the longer the VBAT trace is, the wider it will be. In addition, in order to get a stable power source, it is suggested to use a TVS with low leakage current and suitable reverse stand-off voltage, and also it is recommended to place it as close to the VBAT pins as possible. The following figure shows the star structure of the power supply. Figure 5: Star Structure of the Power Supply BG95_Series_Hardware_Design 40 / 106 LPWA Module Series BG95 Series Hardware Design 3.5.3. Monitor the Power Supply AT+CBC command can be used to monitor the VBAT_BB voltage value. For more details, see document
[2]. 3.6. Turn on and off Scenarios 3.6.1. Turn on Module Using the PWRKEY Pin The following table shows the pin definition of PWRKEY. Table 8: Pin Definition of PWRKEY Pin Name Pin No. Description DC Characteristics Comment PWRKEY 15 Turns on/off the module Vnorm = 1.5 V VILmax = 0.45 V The output voltage is 1.5 V because of the voltage drop inside the Qualcomm chipset. When BG95 is in power off mode, it can be turned on by driving PWRKEY low for 5001000 ms. It is recommended to use an open drain/collector driver to control the PWRKEY. A simple reference circuit is illustrated in the following figure. Figure 6: Turn on the Module Using Driving Circuit Another way to control the PWRKEY is using a button directly. When pressing the key, electrostatic strike may generate from the finger. Therefore, a TVS component is indispensable to be placed nearby the button for ESD protection. A reference circuit is shown in the following figure. BG95_Series_Hardware_Design 41 / 106 LPWA Module Series BG95 Series Hardware Design Figure 7: Turn on the Module Using Keystroke The power on scenario is illustrated in the following figure. Figure 8: Power-on Timing NOTES 30 ms. 1. Make sure that VBAT is stable before pulling down PWRKEY pin and keep the interval no less than BG95_Series_Hardware_Design 42 / 106 LPWA Module Series BG95 Series Hardware Design 2. PWRKEY output voltage is 1.5 V because of the voltage drop inside the Qualcomm chipset. Due to platform limitations, the chipset has integrated the reset function into PWRKEY. Therefore, never pull down PWRKEY to GND permanently. 3.6.2. Turn off Module Either of the following methods can be used to turn off the module:
Turn off the module through PWRKEY. Turn off the module through AT+QPOWD command. 3.6.2.1. Turn off Module through PWRKEY Driving PWRKEY low for 6501500 ms and then release it, the module will execute power-down procedure. The power-off scenario is illustrated in the following figure. Figure 9: Power-off Timing 3.6.2.2. Turn off Module through AT Command It is also a safe way to use AT+QPOWD command to turn off the module, which is similar to turning off the module via PWRKEY. See document [2] for details about AT+QPOWD command. BG95_Series_Hardware_Design 43 / 106 LPWA Module Series BG95 Series Hardware Design 3.7. Reset the Module RESET_N is used to reset the module. Due to platform limitations, the chipset has integrated the reset function into PWRKEY, and RESET_N connects directly to PWRKEY inside the module. The module can be reset by driving RESET_N low for 23.8 s. Table 9: Pin Definition of RESET_N Pin Name Pin No. Description DC Characteristics Comment RESET_N 17 VILmax = 0.45 V Resets the module Multiplexed from PWRKEY (connected directly to PWRKEY inside the module).

BG95_Series_Hardware_Design 47 / 106 LPWA Module Series BG95 Series Hardware 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. 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. If the system ground plane is complete, USIM_GND can be connected to the system ground directly. To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away from each other and shield them with surrounded ground. USIM_RST should also be ground shielded. In order to offer good ESD protection, it is recommended to add a TVS diode array with parasitic capacitance not exceeding 15 pF. In order to facilitate debugging, it is recommended to reserve series resistors for the (U)SIM signals of the module. 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 line can improve anti-jamming capability when long layout trace and sensitive occasion are applied, and should be placed close to the (U)SIM card connector. NOTES 1. eSIM function is optional. If eSIM is selected, then the external (U)SIM cannot be used simultaneously. 2. BG95-M5 and BG95-M6 do not support eSIM. 3.10. USB Interface BG95 contains one integrated Universal Serial Bus (USB) interface which complies with the USB 2.0 specification and supports operation at low-speed (1.5 Mbps) and full-speed (12 Mbps) modes. The USB interface is used for AT command communication, data transmission, software debugging and firmware upgrade. The following table shows the pin definition of USB interface.

The USB interface is recommended to be reserved for firmware upgrade in application designs. The following figure shows a reference design of USB interface. Figure 16: Reference Design of USB Interface In order to ensure the integrity of USB data line signal, components R1 and R2 should be placed close to the module. The extra stubs of trace must be as short as possible. The following principles should be complied with while designing the USB interface, so as to meet USB 2.0 specification. 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 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 lines, so please 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. NOTE BG95 can only be used as a slave device. BG95_Series_Hardware_Design 49 / 106 LPWA Module Series BG95 Series Hardware Design 3.11. UART Interfaces The module provides three UART interfaces: the main UART, debug UART and the GNSS UART interfaces. Features of them are illustrated below:
The main UART interface supports 9600 bps, 19200 bps, 38400 bps, 57600 bps, 115200 bps, 230400 bps, 460800 bps and 921600 bps baud rates, and the default is 115200 bps. It is used for data transmission and AT command communication, and supports RTS and CTS hardware flow control. The default frame format is 8N1 (8 data bits, no parity, 1 stop bit). The debug UART interface supports a fixed baud rate of 115200 bps, and is used for software The GNSS UART interface supports 115200 bps baud rate by default, and is used for GNSS data debugging and log output. and NMEA sentences output.

Reference Design of Main Antenna Interface A reference design of main antenna interface is shown as below. It is recommended to reserve a -type matching circuit for better RF performance, and the -type matching components (R1/C1/C2) should be placed as close to the antenna as possible. The capacitors are not mounted by default. BG95_Series_Hardware_Design 65 / 106 LPWA Module Series BG95 Series Hardware Design Figure 25: Reference Design of Main Antenna Interface 5.1.4. Reference Design of RF Layout For users PCB, the characteristic impedance of all RF traces should be controlled to 50 . The impedance of the RF traces is usually determined by the trace width (W), the materials dielectric constant, height from the reference ground to the signal layer (H), and the clearance 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 26: Microstrip Design on a 2-layer PCB BG95_Series_Hardware_Design 66 / 106 LPWA Module Series BG95 Series Hardware Design Figure 27: Coplanar Waveguide Design on a 2-layer PCB Figure 28: Coplanar Waveguide Design on a 4-layer PCB (Layer 3 as Reference Ground) Figure 29: Coplanar Waveguide Design on a 4-layer PCB (Layer 4 as Reference Ground) BG95_Series_Hardware_Design 67 / 106 LPWA Module Series BG95 Series Hardware Design In order to ensure RF performance and reliability, the following principles should be complied with in RF layout design:
Use an impedance simulation tool to accurately control the characteristic impedance of RF traces to The GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully 50 . 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. 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 as wide as 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 [4]. 5.2.

For authentic appearance, see the module that you receive from Quectel. BG95_Series_Hardware_Design 95 / 106 LPWA Module Series BG95 Series Hardware Design 8 Storage, Manufacturing and Packaging 8.1. Storage BG95 series 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 2. The storage life (in vacuum-sealed packaging) is 12 months in Recommended Storage Condition. should be 35 % to 60 %. 3. The floor life of the module is 168 hours 1) 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. 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. 5. BG95_Series_Hardware_Design 96 / 106 LPWA Module Series BG95 Series Hardware Design NOTES 1. 1) This floor life is only applicable when the environment conforms to IPC/JEDEC J-STD-033. 2. To avoid blistering, layer separation and other soldering issues, it is forbidden to expose the modules to the air for a long time. If the temperature and moisture do not conform to IPC/JEDEC J-STD-033 or the relative moisture is over 60 %, it is recommended to start the solder reflow process within 24 hours after the package is removed. And do not remove the packages of tremendous modules if they are not ready for soldering. 3. Take the module out of the packaging and put it on high-temperature resistant fixtures before the baking. If shorter baking time is desired, refer to IPC/JEDEC J-STD-033 for baking procedure. 8.2. 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. The force on the squeegee should be adjusted properly so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the thickness of stencil for the module is recommended to be 0.130.15 mm. For more details, please refer to document [5]. It is suggested that the peak reflow temperature is 238246 C, and the absolute maximum reflow temperature is 246 C. To avoid damage to the module caused by repeated heating, it is strongly recommended that the module should be mounted 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. Temp.

Multi-slot classes are product dependent, and determine the maximum achievable data rates in both the uplink and downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots, while the second number indicates the amount of uplink timeslots. The active slots determine the total number of slots the GPRS device can use simultaneously for both uplink and downlink communications. The description of different multi-slot classes is shown in the following table.
