Gpio Interfaces - Quectel BG96 Manual

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%.

3.17. GPIO Interfaces

The module provides two general-purpose input and output (GPIO) interfaces. AT+QCFG="GPIO"
command can be used to configure corresponding GPIO pin's status. For more details about the AT
command, please refer to document [2].
