Power Output #26

Hi, I power the board with 5V 3A over USB. The output voltage (that is supposed to power the display) only reaches 1,6V. Am I missing something?

Have you enabled the jumper for USB power?

Yes, I have.

witnessmenow commented 10 months ago

What type of display are you trying to power or how many displays? What voltage do you see when there is no displays attached?

laserir commented 10 months ago

Believe it or not... faulty USB cable... so stupid, sorry to bother :D

No worries, glad it's working!
