It measures 160 × 160 mm and has 2 copper layers, 1.6 mm thick.
42 parts, built around the 74HC04D, TB002-500-03BE and BD139. 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 KremerMichael/chen-lab-PCB repository on GitHub, at the commit this page was made from: the board is board-design/cage-board.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 KremerMichael before reusing the design.
