It measures 44.4 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
11 parts, built around the BC548. 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 UCFInnovationLab/GLAMPING_2025 repository on GitHub, at the commit this page was made from: the board is blinkingLight/blinkingLight.kicad_pcb and its schematic blinkingLight/blinkingLight.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 UCFInnovationLab before reusing the design.
