The 14 most common of 17 parts.
17 parts, built around the AO3401A, BS-04-A1BJ004 and TMB12A03. 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 DougTomanio/beeping-easter-egg repository on GitHub, at the commit this page was made from: the board is beeping-easter-egg.kicad_pcb and its schematic beeping-easter-egg.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 DougTomanio before reusing the design.
