It measures 150 × 50 mm and has 2 copper layers, 1.6 mm thick.
19 parts, built around the IRF3205 and UF4007. 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 DavidBojanovic08/Magic-wand repository on GitHub, at the commit this page was made from: the board is Magic wand - electroboom.kicad_pcb and its schematic Magic wand - electroboom.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 DavidBojanovic08 before reusing the design.
