Questions
How big is the St12 PCB?
It measures 136.8 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the St12 use?
81 parts, built around the OPA237NA/250G4, TPS5430DDAR, 24LC1025-I/P and AMS1117-3.3. 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 St12 KiCad files?
From the kloper/st12 repository on GitHub, at the commit this page was made from: the board is kicad/st12.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the St12 design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
