It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
16 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 Jamesits/pi-hat-spi-reader repository on GitHub, at the commit this page was made from: the board is pi-hat-spi-reader.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 Jamesits before reusing the design.
