I've had an MB burn up two RasPi's. Same symptoms - way too hot with way too much voltage into the Pi. I'm betting it's the square chip slightly above the mini-USB connector - RG2 - that's doing the heating up. That's the chip that got so hot on mine - so hot it heats up everything around it. Two fried PIs...
Ah yes I remember you mentioned something about this in the past. What did you end up doing? I emailed Dave to see what he can do about the board and RPi
I also lost an rpi, it was cooked dead, wont power up by any means. I had a spare pi but no spare M-board. running almost 2 days now on backup. I have reached out to MBP about this and am still waiting for response. I also have more rpi on the way, just in case.
Ah geez I'm doing some research on this... interesting that on the raspberry pi forums, feeding power into the GPIO pins (like how our mboards are doing) is not recommended because it doesn't have any power protection.
Not suggesting this but, If the pins that power the pi were dissabled (snipped, bent, whatever), And we then power the pi via wall-wart, would it work? Or are those pins serving another purpose. I fully realize a modification to the M-board will void the warranty, Just an out loud thought turned into a post.
Also I dont like this Idea just from the point of having another plug.
