It measures 13.5 × 13 mm and has 2 copper layers, 1.6 mm thick.
9 parts, built around the VCNL4200. 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 kuellenberg/Adapter-VCNL4200 repository on GitHub, at the commit this page was made from: the board is Adapter-VCNL4200.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 kuellenberg before reusing the design.
