Table 21: Pin Definition of ADCInterfaces
The following table describes the characteristics of ADC interfaces.
Table 22: Characteristics of ADC Interfaces
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, andthe divider resistor accuracy
should be no less than 1%.
3.17. GPIOInterfaces
The module provides two general-purpose input and output(GPIO) interfaces. AT+QFWD* command can
be used toconfigure corresponding GPIO pin’s status. For more details about the AT command, please
refer to document [2].
