It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
6 parts. 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 jamesfowkes/cryptology-countdown repository on GitHub, at the commit this page was made from: the board is controller/controller.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 jamesfowkes before reusing the design.
