It measures 76.5 × 76.5 mm and has 2 copper layers, 1.6 mm thick.
4 parts, built around the MPR121QR2. 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 LyndLabs/Edge-AI-Badge_Firmware repository on GitHub, at the commit this page was made from: the board is hardware/frontplate/Edge-AI-Badge_Frontplate/Edge-AI-Badge_Frontplate.kicad_pcb and its schematic hardware/backplate/Edge-AI-Badge_Backplate.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 LyndLabs before reusing the design.
