Adafruit USB Type C CC Resistor Fixer
We have ✅ 1 available of the AF-6323 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit USB Type C CC Resistor Fixer solves a common problem: USB-C devices that won't power or communicate when plugged into another USB-C port. Many devices are missing the two 5.1K CC (Configuration Channel) resistors required for proper USB C-to-C negotiation at 5V — this inline adapter adds them for you.
Simply plug it between your USB-C cable and the misbehaving device. The fixer passes through the two data pins plus VBUS and ground power lines, while adding the missing 5.1K CC resistors on the port side. A power good LED confirms when the connection is working.
Key Features
- Adds Missing CC Resistors – Provides the 5.1K CC1 and CC2 resistors required for USB C-to-C 5V connections
- Inline Design – USB-C socket and plug for easy cable pass-through
- Power Good LED – Visual confirmation that the connection is active
- Data Pass-Through – Carries D+ and D- data lines plus VBUS and GND
- Compact PCB – Small enough to fit onto a cable or into a port
Ideal For
- Fixing USB-C devices that won't charge or connect via C-to-C cables
- Devices that work with USB-A to C adapters but fail with C-to-C cables
- Quick diagnosis of CC resistor issues on USB-C hardware
