    Hello.Still working on this problem little by little each day, reading and studying. The main thing I'm trying to accomplish now is following the 5 volts from the usb-c jack and see where it stops.

    Can you identify what kind of diode this is?

    I believe the diodes in this picture are are back to back avalanche diodes in one package. What is the purpose of this setup? I'm assuming one of these is the usb-c protection chip (if this board has one that is).
