Questions
How big is the Usb uart plug PCB?
It measures 34.4 × 12.7 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Usb uart plug use?
22 parts, built around the CH334R. 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 plug KiCad files?
From the Finomnis/usb-uart-plug repository on GitHub, at the commit this page was made from: the board is usb-uart-plug/usb-uart-plug.kicad_pcb and its schematic usb-uart-plug/usb-uart-plug.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb uart plug 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).
