Blown input voltage protection diode
I've accidentally put too much voltage (>6v) on the Vin, and blown the voltage input protection diode. I can't seem to locate it on the board. Any ideas as to it's location, and how to verify? Excellent close up pictures of the main board are shown in the teardown guide, step 13. The battery in prongs are the 3 gold fins surrounded by black at the bottom of pic 2. I think the diode should be nearby, but I can't identify it. Perhaps the diode marked "BB"?
Lots of thanks for a clue!
Is this a good question?
