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. 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.
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. 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.
8. Keep all RESERVED pins and unused pins unconnected.
9. Connect GND pins to the ground in the design.
