It measures 97.5 × 39.3 mm and has 2 copper layers, 1.6 mm thick.
40 parts, built around the PCA9535D. 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 GreHack/CTF-challs repository on GitHub, at the commit this page was made from: the board is 2019/Hardware/PCB/SAO/GreHack2019-SAO-V2.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 GreHack before reusing the design.
