Questions
How big is the USBtoSerial PCB?
It measures 28.7 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USBtoSerial use?
34 parts, built around the MAX3232ID, FT232RQ and MCP2200-I/SS. 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 USBtoSerial KiCad files?
From the serra82/USB2serial repository on GitHub, at the commit this page was made from: the board is USBtoSerial.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBtoSerial design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
