It measures 90 × 90 mm and has 4 copper layers, 1.61 mm thick.
187 parts, built around the LAN8742A-CZ, MYBSP00502ABF, SRV05-4 and AMS1117-3.3. 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 tweedegolf/spaeter repository on GitHub, at the commit this page was made from: the board is hardware/node-prototype/node-prototype.kicad_pcb and its schematic hardware/node-prototype/debug.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 tweedegolf before reusing the design.
