It measures 31.8 × 36.8 mm and has 2 copper layers, 1.6 mm thick.
12 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 StarGate01/Handbrake repository on GitHub, at the commit this page was made from: the board is Hardware/Handbrake.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask StarGate01 before reusing the design.
