Yep, it looks like I'm that retarded. I was in the process of wiring up a USB plug up to my quad to power my GoPro. Well, I mistakenly hooked it up to 12V direct from the battery instead of regulated 5V and POP it went. A bit of smoke even came out the USB port.
Of course, after that it wouldn't turn on and got very hot if I plugged it into USB power.
Looking closely at this however it looks like all the components are still there. The circle below C1 is just a locating hole for the lens assembly.
Closer inspection of all the boards reveal that this charred spot was likely caused by an exploding capacitor on the board mounted in front of it.
So I may try replacing this component and see how I go. Like I said, nothing to loose at this point. All the capacitors on this footprint seem to be the same value (100 6K, whatever that means), so I'll try that first. Anyone got a dead GoPro I can scavenge from?
Not doing too well this week, smashed my iPhone screen two days ago and now this. At least I know I can repair my iPhone. Anyone else done something this stupid?
