#12 Update: Making USB-C deliver 5V

After some googling and some testing I finally figured out that the lines CC1 and CC2 are shorted on these breakout boards. Severing the connection between them and adding two pull-down resistors makes it a usable 5V connector. You will also probably need 1206 size resistors for the reverse side: https://s.click.aliexpress.com/e/_AAAqGp
