I recently started building a 250 quad and decided to use the brand new OP Revolution board that I bought when they were first released as a beta. (somehow I never got around to installing it. ) Anyhow, I got it configured and it was performing quite nicely. Decided to add the a satellite RX, then Oplink, then the GPS. Did I mention that I was using opto ESC's? This meant adding voltage reducers... A 3.3V for the satellite, and a 5V for the GPS. Then of course I decided to add voltage monitoring... By the time I was done, I had quite a nice mess of wiring coming from the PDB. Everything worked fine!!

Decided to calibrate all the sensors so I took it all apart and did the calibrations...then I put it back together. Was trying to plug the microUSB into that small socket buried deep within the quad when I did a BooBoo   A little spark and the magic smoke came out of my board.

Well, obviously it isn't working anymore... My question is, is there anyone or anyway to repair this? Is there a part that would be first to go and could possibly be replaced that might breath life into my board? When I plug the USB in, I get no LEDs and the smd's get hot real fast. Just kinda hoping that this board isn't destined for the trash...

Do you see any components that are "fried"?Maybe those are replaceable. 

Can you share some close up pics?

There's documentation about which component is what and where in the git repository: https://bitbucket.org/librepilot/librepilot/src/4f5dd7117c7b632d8113a588627a9eb294adbca0/hardware/Production/OpenPilot%20Revolution/?at=next

Awesome..


Thanks so much. I will try to post some pictures this evening.

Here are the pictures of my non-functioning Revolution. Unfortunately, my macro lens is at the office, so I hope these pics will suffice. Any ideas on what part I may have smoked???

I don't see anything obvious (apart from the broken antenna connector)

You said some SMDs get hot. Which ones?

It could be just a busted VReg or something...

Same as for CC3D I suspect its the voltage regulator chips that beak first in these situations, often not visible. You have to check them with a multimeter somehow. Im not a good enough electrician to know how but a friend of mine fixed and replaced it on one o my CC3D once. 

the small black thingie with 3 arms on one side and 2 on the other, there looks to be one on the top and two on the other side.
