Is there any reference documentation for the 40-pin connector on the 4G-IOT board?

Also, is it possible to use both the microphone input on the audio jack and the onboard microphone to receive two separate input sources, or are they mutually exclusive?

The schematics are in the download with the user manual.

Ok, I'll take another look at those. Thanks.
