Questions
How big is the Term4pi PCB?
It measures 23.5 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Term4pi use?
22 parts, built around the CP2102N-A01-GQFN24. 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 Term4pi KiCad files?
From the Matir/hacks repository on GitHub, at the commit this page was made from: the board is pcbs/term4pi/term4pi.kicad_pcb and its schematic electronics/wiretest/wiretest/wiretest.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Term4pi design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
