It measures 47.3 × 46.7 mm and has 2 copper layers, 1.6 mm thick.
55 parts, built around the 74HC595. 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 12voltman/SimulType repository on GitHub, at the commit this page was made from: the board is Hardware/devtools/simultypecontrol/simultypecontrol.kicad_pcb and its schematic Hardware/controlboards/SimulTypeHeaderUltra/SimulTypeHeaderUltra.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
