Hi, I need to replace this circuit board where the charging port mounts.

While trying to remove damaged micro usb port, I damaged the tiny wires from the circuit board.

I tried to find this online but no luck so far.

Do you know the code for this PCB?

Thank you,

I have a question on the small circuit board (charge port), one of the female port on it is for power (+5v), but what is another one? Is it D+, D- ?

P.S. I’ve measure that port with micro usb connected to power source, turns out there has no voltage measured, but the bigger one does has 5v measured.

Thanks!
