The 31 most common of 33 parts.
It measures 76.3 × 27.2 mm and has 2 copper layers, 1.6 mm thick.
33 parts, built around the CM108AH, AMS1117-3.3 and AMS1117-5.0. 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 mariosgit/M3D4 repository on GitHub, at the commit this page was made from: the board is PCB-KICAD/M3D4/M3D4.kicad_pcb and its schematic PCB-KICAD/M3D4/M3D4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask mariosgit before reusing the design.
