It measures 73 × 50 mm and has 6 copper layers, 1.6 mm thick.
24 parts, built around the ATTINY13-20PU. 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 Susensio/soft-starter repository on GitHub, at the commit this page was made from: the board is schematics/soft-starter.kicad_pcb and its schematic schematics/soft-starter.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 Susensio before reusing the design.
