NOTE
It is recommended to reserve the above circuit design during application design.

3.16. ADC Interfaces

The module provides two analog-to-digital converter (ADC) interfaces. 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 these AT commands, please refer to document [2].
In order to improve the accuracy of ADC voltage values, the trace of ADC should be surrounded by
ground.
