VAUX Power Output
A regulated power supply output is provided to supply small devices from the module.
This output is active when the module is ON and goes OFF when the module is shut
down. The operating range characteristics of the supply are as follows:

Description
The LE940B6 module provides three on-board 12-bit Analog to Digital converters. Each
ADC reads the voltage level applied on the relevant pin, converts it and stores it into a 16-
bit word.

Using the ADC Converter
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 Ref 1: LE940B6 AT Command Reference Guide for the full description of this
function.
Using the Temperature Monitor Function
The Temperature Monitor supports temperature monitoring by giving periodic temperature
indications, to execute some function at extreme state. If properly set (see the
#TEMPMON command in Ref 1: LE940B6 AT Command Reference Guide), it raises a
GPIO to High Logic level when the maximum temperature is reached.
