I have a Hobbyking PDB which includes a power module on it. It's been working fine for a week but today it fried 2 of my pixhawk clones. Upon closer examination, the power module is outputting raw battery voltage and since I had a 4s battery plugged in at the time, the power module was outputting >16v to the pixhawk. Before I knew this, because my first pixhawk wasn't working I decided to plug a second pixhawk in to see if I could figure out what the problem was... Bad idea. Magic smoke appeared.
The partially good news is that both pixhawks can be powered via USB and I'm wondering if there's something I can replace on the pixhawk PCB to get these pixhawks back in action again? I'm assuming that a fuse has blown?
Here's a video of the power module outputting 16v: https://youtu.be/LZousFKWpgs
Here's a photo of the pixhawk clone:
Obviously I've been in contact with Hobbyking and I'm seeking some kind of compensation but it would be a shame to have to throw these in the bin...
I'd really appreciate some assistance if possible.
