It measures 50 × 100 mm and has 2 copper layers, 1.6 mm thick.
22 parts, built around the B4B-XH-A(LF)(SN). 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 Farex-GH/Open-Genbu-GC repository on GitHub, at the commit this page was made from: the board is PCB/pico-pcb/pico-pcb.kicad_pcb and its schematic PCB/front-panel/front-panel/front-panel.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 Farex-GH before reusing the design.
