Adc Interfaces; Gpio Interfaces - Quectel BG95 Manual

4.11. ADC Interfaces

BG95/BG96 provides two analog-to-digital converter (ADC) interfaces. But the ADC0 and ADC1 for BG95
are internally connected, therefore they cannot be used simultaneously. If the two ADC interfaces of
BG95 are intended to be used at the same time, please add an external analog switch.
For BG95, AT+QADC=0 command can be used to read the voltage value on the ADC being used. For
more details about the AT command, please refer to document [3].
For BG96, AT+QADC=0 command can be used to read the voltage value on ADC0 pin. AT+QADC=1
command can be used to read the voltage value on ADC1 pin. For more details about the AT command,
please refer to document [4].
For more details about the ADC interfaces of BG95/BG96, please refer to document [1] and [2].
NOTES
1. ADC input voltage must not exceed 1.8V.
2. It is prohibited to supply any voltage to ADC pins when VBAT is removed.
3. It is recommended to use resistor divider circuit for ADC application, and the divider resistor accuracy
should be no less than 1%.

4.12. GPIO Interfaces*

Both BG95 and BG96 provide general-purpose input and output (GPIO) interfaces.
For BG95, the module provides nine general-purpose input and output (GPIO) interfaces.
AT+QCFG="gpio"* command can be used to configure the status of corresponding GPIO pins. For more
details about the AT command, please refer to document [3].
For BG96, the module provides two general-purpose input and output (GPIO) interfaces. AT+QFWD
command can be used to configure corresponding GPIO pin's status. For more details about the AT
command, please refer to document [4].
For more details about the GPIO interfaces of BG95/BG96, please refer to document [1] and [2].
