@dc42 aha ok! I have to do that at work where we have a hot air solder gun
@dc42 You mean the U11 / 74HCT02?
@bearer I connected 3.3V to where the regulater output was.
@dc42 I connected 3.3V and nothing got hot.
When I connected USB I got 4.4V in the 3.3V rail...
I've removed U2, where can I connect 3.3V and what should I set the current limit to?
Btw, I tried the SD card and it seems to work fine.
@bearer Yeah, that's what I tought.. Could it be fixed if I just replaced U2?
What does U2 do?
@dc42 I can't find the 74HCT02 chip.
The only component that seems off is this one.
@dc42 do you think mt duex2 got damage as well?

If I connected 12VDC there (beautiful red arrow), am I screwed then?
How screwed am I if I manage to connect 12VDC on the 5VDC rail?
