Table 22: Pin Definition of ADC Interface
The following table describes the characteristics of ADC interface.
Table 23: Characteristics of ADC Interface
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 resistor accuracy
should be no less than 1%.
2.18 GPIO Interfaces*
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 [2].
