It measures 81.9 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
34 parts, built around the DM02. 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 runshine/hardware_FanPWMControl repository on GitHub, at the commit this page was made from: the board is FanPWMControl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask runshine before reusing the design.
