After a slight indiscretion with some wiring, I managed to hook my powersupply up to my 'pi with reversed polarity. I spotted it fairly quickly when nothing powered up, but it was too late…
The 'pi did work again for a few minutes then the smoke escaped, from the small (10?) pin package under the little bit of black tape. Being a power problem, and so close to a honking great inductor, I suspect this is the switcher for the Vboost converted.
So that I dont have to toss my 'pi in the bin, can anyone tell me what the part is so I can replace it?
I do have a second (and third) 'pi, but i cant make head nor tale of the markings on it.
