    A client of mine and I custom mounted a FLiR Vue Pro to his Phantom 2: Zenmuse H4-3D. After numerous balancing issues we got the setup to function nicely.

    The first few test flights went fine but on the most recent startup I got a miniscule puff of of smoke from the power con board mounted underneath the bird.

    Upon immediate power down and a closer inspection it looks as if something on the power con board "popped" like friggen Pringles lid. (See attached) Everything else seems fine. Any thoughts guys?

    That's an anti-interference board (analogue) used to minimise FPV static.
    They are cheap and sometimes not required as you can plug the H3-3D directly from the main board to the gimbal. I'd suggest you get another as whatever you are doing, its causing a short out somewhere. The anti-interference board acted like a fuse and probably saved your main board from frying.

    The AI boards are about $30.

    Yeah I had a feeling a short was the culprit but I'm having a heck of a time tracking it down.

    We're talking about a pretty standard p2 Zenmuse setup here except were running the flir cam and a set of KDE Direct motors and esc's.
