The HE910 V2 provides one Analog to Digital Converter.
The input lines are:
ADC available on pin B1 and Pin 7 of PL102 on Interface Board (CS1467D)
An AT command is available to use the ADC function.
The command is AT#ADC=1,2. The read value is expressed in mV
Refer to SW User Guide or AT Commands Reference Guide for the full description of this
function.
