It measures 18.8 × 36.6 mm and has 2 copper layers, 1.6 mm thick.
14 parts, built around the ATSAML11E15A-MU. 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 EnJens/securisam repository on GitHub, at the commit this page was made from: the board is securisam.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 EnJens before reusing the design.
