Adafruit USB Type C CC Resistor Fixer
The Adafruit USB Type C CC Resistor Fixer is a tiny PCB that inserts the missing two 5.1 kΩ configuration channel resistors required for proper 5 V C-to-C power negotiation, adding a power-good LED while passing data, Vbus and ground lines. It fits onto a cable or into a mis-designed port, supporting only USB charge/sync functions and not high-speed or specialty protocols.
