The 158 most common of 160 parts.
It measures 74 × 104 mm and has 4 copper layers, 1.59 mm thick.
160 parts, built around the RP2040, AP2112K-3.3, LS027B7DH01 and ME6212C18M5G. 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.
From the sqfmi/beepy-hardware repository on GitHub, at the commit this page was made from: the board is KiCad/beepy.kicad_pcb and its schematic KiCad/bbq20kbd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
