It measures 80 × 30 mm and has 2 copper layers, 1.6 mm thick.
25 parts, built around the ATTINY85-20PU. 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 jdppcb/Pedale_USB_Espace repository on GitHub, at the commit this page was made from: the board is Kicad/PUS_K9.kicad_pcb and its schematic Kicad/PUS_K9.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 jdppcb before reusing the design.
