It measures 154 × 123 mm and has 2 copper layers, 1.6 mm thick.
61 parts, built around the TSR 1-2450, 74HC595, NE555P and ULN2803A. 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 daliborr1/Blinker-light-project-pcb repository on GitHub, at the commit this page was made from: the board is 1.kicad_pcb and its schematic 1.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 daliborr1 before reusing the design.
