If I know I won’t be using HDMI out, is it safe to:
set the HDMI toggle switch to “OFF” on the board
unplug the internal 3.5mm audio cable (both ends)
unplub the internal USB-microUSB cable (both ends)
Finally, remove the ADC unit from the internal DSUB connector
There’s obviously nothing being desoldered here or cut, so it seems safe, but I just wanted to make sure the software or power wiring doesn’t expect the ADC unit to be present for one reason or another?
