Rock pi V1.4 over current on 0.1 ohm resistor

[jack]

It’s mostly like you need to change the NB679GD IC. We had experience before which 19V DC input burnt the NB679GD, check this thread:

Power supply for the rockpi

Prob should work but it might be like some of the Dells that has a sort of early proprietary PD protocol. I have tested with various dumb 12vdc smps and it works fine. It copes with 20V I am sure as long as the polarity is correct might even have a diode to protect but not sure.
