It measures 66.7 × 85.7 mm and has 2 copper layers, 1.6 mm thick.
22 parts, built around the SK6812MINI-E. 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 STOP-DA-CAP/Arshas_macropad repository on GitHub, at the commit this page was made from: the board is Macropad_PCB/Macropad_PCB.kicad_pcb and its schematic Macropad_PCB/Macropad_PCB.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 STOP-DA-CAP before reusing the design.
