If i was to solder a battery (and maybe a switch) to my #corne and i don't want to solder to the MCU, can i hijack the TRRS pins since they should also route V+ and GND? It is a classic v2 PCB.
Looking at the kicad file would be a last resort to me, since i am not good at that (yet).
I am sure somebody has done that before?
