The MIC/TV pads lack a standardized connector so you either have to mount one or use jumper
wires.
The MIC/TV jack hasn't been fully tested on software level.

Signals marked with * are multiplexed with either a peripheral device or another connector. Ensure that the multiplexing is handled
properly on software and/or hardware level (else there would probably occur wrong levels, loss of data, etc).
6.13 GPIO-2 (General Purpose Input/Output) 40pin connector
The GPIO pins are led out on a separate 40pin connecter. They allow the user to attach additional
hardware, check readings or perform hardware debug. The GPIO-2 connector numbers are printed
