Questions
How big is the USB232R02 PCB?
It measures 40.1 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB232R02 use?
28 parts, built around the FT231XQ-R and USBLC6-2SC6. 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 USB232R02 KiCad files?
From the serptail/USB2UART-KiCad-PCB-Design repository on GitHub, at the commit this page was made from: the board is design/sch_pcb/USB232R02.kicad_pcb and its schematic design/sch_pcb/USB232R02.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB232R02 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).
