It measures 82.5 × 101.6 mm and has 2 copper layers, 1.6 mm thick.
57 parts, built around the ATMEGA328-PU and CH340G. 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 gtetil/USBdio-PCB repository on GitHub, at the commit this page was made from: the board is USBdio-PCB.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 gtetil before reusing the design.
