It measures 69.6 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
16 parts, built around the BC337. 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 marengo560/CameraIntervalometer repository on GitHub, at the commit this page was made from: the board is PCB/CameraIntervalometer/CameraIntervalometer-backups/CameraIntervalometer.kicad_pcb and its schematic PCB/CameraIntervalometer/CameraIntervalometer-backups/CameraIntervalometer.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 marengo560 before reusing the design.
