LPWA Module Series
BG95 Series Hardware Design

1.
1)
Only BG95-MF supports ANT_WIFI (pin 56).
2.
2)
BG95-MF does not support GPIO3 and GPIO4 interfaces (pin 64 and pin 65).
3.
3)
BG95-M4 does not support GRFC interfaces (pin 83 and pin 84).
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.
