The 153 most common of 160 parts.
It measures 114.3 × 98.8 mm and has 2 copper layers, 1.6 mm thick.
160 parts, built around the ATMEGA32U4-AU, BAV70, PRTR5V0U2X and 1206L110THYR. 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 Duckle29/MS40 repository on GitHub, at the commit this page was made from: the board is mystic_split40.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the BSD-3-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).
