PCB & 3D
CC Resistors
For the device to work with USB-C to USB-C cables, you must add two resistors to the configuration pins:
- CC1 (Pin A5): Connect a 5.1kΩ resistor to GND.
- CC2 (Pin B5): Connect a 5.1kΩ resistor to GND.

Questions
How big is the USB UART PCB?
It measures 39 × 19 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB UART use?
19 parts, built around the FT232RL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the USB UART KiCad files?
From the wirenux/USBC-UART repository on GitHub, at the commit this page was made from: the board is USB-UART.kicad_pcb and its schematic USB-UART.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB UART design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
