It measures 61.2 × 49.1 mm and has 2 copper layers, 1.6 mm thick.
49 parts, built around the LMH0307SQ and BSS138. 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 q3k/inputkatze repository on GitHub, at the commit this page was made from: the board is kicad/designs/sdi-devboard/sdi-devboard.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 q3k before reusing the design.
