The 10 most common of 12 parts.
It measures 35.6 × 65.7 mm and has 2 copper layers, 1.6 mm thick.
12 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 twyleg/wirebug_hardware repository on GitHub, at the commit this page was made from: the board is wirebug.kicad_pcb and its schematic wirebug.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 twyleg before reusing the design.
