Adafruit USB-C CC Resistor Fixer
Do you have any devices with USB C connections that don't seem to power or work when plugged into another USB C port? Chances are, the designers skimped a few pennies or just forgot to put inĀ the two 5.1K CC resistors required for C-to-C connectionsĀ at 5V. It can drive you batty because some computers care and some don't!
That's why we designed theĀ Adafruit USB Type C CC Resistor Fixer, a collab between ourĀ sunken USB socketĀ andĀ USB Plug breakout. It's the onlyĀ product we hope we can discontinue one day, sooner rather than later!Ā This small PCB assembly fits onto a cable or into the mis-designed port. It passes through the two data pins and the Vbus and Ground power lines, while adding the missing 5.1K resistors on the port side and a power good LED.
Note that the USB plug pinout doesn't carry the sideband wires or the high-speed pins, so this is good for USB charge/sync but not for high speed or speciality protocols. If you're not sure, then it's very unlikely you need them: those products aren't going to mess up the CC resistors.
Snap-on enclosure now available!
