I have pulled one of my puck.js out of the draw again recently and have tried to drive it with a 3.3v power source for prototyping. Not sure what I am going to do with it but I would prefer not to burn through my batteries while prototyping so I have soldered on some headers and tried driving it through GND and 3v pins but this board has had some abuse and I didn't know how to solder when I orginally got it and it seems I damaged the trace...
Anyway, my question is can I use D24 and D23 for power connection?
I recall that they were supposed to be for external battery connection but can't find any info about it.
e.g. which one is GND?
