So, if I used a switch pulled to 12V and used ADC to detect going to 0V, that would be OK with the board hardware? no, analog input range is dc 0-5v, can't connect with dc12v.
Or, could I use GPIO33 (GSMTX) and GPIO14 (GSMRX) from the P2 HMI header? if you want use for HMI , also is ok, such as Nextion display is supported.
