It measures 145.1 × 182.1 mm and has 2 copper layers, 1.6 mm thick.
90 parts, built around the 1N4148W. 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 anton2785-bit/Split_keyboard_Macondo repository on GitHub, at the commit this page was made from: the board is PCB/Split_keyboard_macondo.kicad_pcb and its schematic PCB/Split_keyboard_macondo.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 anton2785-bit before reusing the design.
