Everything was going fine. ESCs calibrated, motors turning the right direction and I was starting to tie up the loose ends. I thought it would be a good idea to attach the X6B to the PDB using one of screws that attaches one of the legs to the PDB.
Once I had the X6B screwed down, I connected the battery for another test run and I got that bad, electrical overheating smell and the PixHawk (PH) failed to start. I quickly pulled the X6B connector out of the PH. I started up the PH w/out the XB6 attached and it seemed to initiate, respond to the press of the starter switch and was ready for the Xmitter to connect.
I unplugged the PH again, pressed the starter button, plugged in the X6B and the PH shut down. I repeated the same several times with the same result.
Question: Have I fried my X6B? If so, is this the right product to reorder? https://tinyurl.com/yy3hkxz6
