It measures 17.8 × 52 mm and has 2 copper layers, 1.6 mm thick.
16 parts, built around the FDN339AN, ITR9606 and JUMPER3. 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 Duckle29/Dual-optical-endstop repository on GitHub, at the commit this page was made from: the board is kicad_project/V1.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 Duckle29 before reusing the design.
