Questions
How big is the Usb2uart PCB?
It measures 39.7 × 22.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb2uart use?
20 parts, built around the CP2110EK and SP0503BAHTG. 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 Usb2uart KiCad files?
From the maximst/usb2uart repository on GitHub, at the commit this page was made from: the board is usb2uart.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb2uart design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
