2.9.3 General Purpose A/D
The module provides 3 additional general purpose A/D (GPAD) signals for customer application use.
Each A/D signal can monitor a separate external voltage and report its measured level independently to
the application, through the AT command interface. The A/D Signals are available at the connector in the
following pins: 37, 43 and 47.
The GPAD signals can sense a DC voltage level of 0 – 2.3 V, which is converted internally to a 10-bit
digital value.
