Gpio Interfaces - Quectel BG772A-GL Hardware Design

NOTES
1. ADC input voltage must not exceed 1.8 V.
2. It is prohibited to supply any voltage to ADC pin when VBAT is removed.
3. It is recommended to use resistor divider circuit for ADC application, and the divider's resistor
accuracy should be no less than 1 %.

3.17. GPIO Interfaces*

The module provides seven general-purpose input and output (GPIO) interfaces. AT+QCFG=
be used to configure the status of GPIO pins. For more details about the AT command, see
document [3].
