The 52 most common of 56 parts.
It measures 47 × 44 mm and has 2 copper layers, 1.6 mm thick.
56 parts, built around the CD4511BNSR and NE555D. 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 hackclub/reflow repository on GitHub, at the commit this page was made from: the board is pcb/reflow-example/reflow-example.kicad_pcb and its schematic pcb/MP3-Player/cad/MP3 Player.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 hackclub before reusing the design.
