Questions
How big is the Big switch PCB?
It measures 76.3 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Big switch use?
23 parts, built around the RP2040-ZERO and SK6812MINI-E. 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 Big switch KiCad files?
From the prapooskur/big-switch-pcb repository on GitHub, at the commit this page was made from: the board is big-switch.kicad_pcb and its schematic big-switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Big switch design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
