Quoted from bobukcat:I've never worked on a node board before but I've always been curious about them, can you do the same continuity tests on a good, working board? If something is shorting 5VDC to ground it could really be a chore to figure out exactly what depending on how many components are on that board.
Just updating, I think we narrowed it down to U14, from what I have been told/read U1 is usually the culprit as to why this board fails, however given that my board isn't even providing the 3.3V to power U1 I suspect it is the step down. We tested all the components we could so I have ordered a replacement chip from element14, once it arrives I will do the swap and see what happens.
