It measures 23.6 × 20 mm and has 2 copper layers, 1.6 mm thick.
21 parts, built around the ATMEGA8A-AU. 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 HDR/XenoGC-Flex repository on GitHub, at the commit this page was made from: the board is XenoGCFlex.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 HDR before reusing the design.
