By accident I put inverse polarity at rockpro64 and these chips near power supply were burnt, can anybody send me the parts names so as to try to replace them?
Did you take a look at the schematic?
I hate to admit that I did the exact same thing with my board (D'oh!).
Im working on repairing mine now, and found that bough "SY8113B" Step Down Regulators where fried, as well as the two parts labelled "3R3" that sit next to them. I
think the "3R3"s are coils, but im not sure. If anyone happens to know what part this is, I would love to know. As far as I can tell, its not listed on the schematic.
Thanks!
