The 22 most common of 23 parts.
It measures 100 × 25 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the NE555P. 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 Shadow220108/PCBSPRINT repository on GitHub, at the commit this page was made from: the board is PCB/PCBSPRINT.kicad_pcb and its schematic PCB/PCBSPRINT.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 Shadow220108 before reusing the design.
