OK so not sure what happened but I'm not getting any voltage from my 3.3v connection on the board. Is there a quick fix to this or did something get shorted out and I'm going to have to get a new board?
Mega2560 has seperate 3.3V regulator, good for 150mA I think (been a while since I looked).
Check its input & output, perhaps you fried it somehow. I think it's a fairly decent sized part that you can attempt to replace yourself.
