46 parts, built around the STSPIN220, TPS62162DSG, EVPAA602W and NCE2060K. 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 stanleyondrus/LaserProjectorV2 repository on GitHub, at the commit this page was made from: the board is hardware/pcb/LaserProjector_REV_04/LaserProjector_REV_04.kicad_pcb and its schematic hardware/pcb/LaserProjector_REV_04/HomingSensor_REV_01/HomingSensor_REV_01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask stanleyondrus before reusing the design.
