It measures 31 × 15 mm and has 2 copper layers, 1.6 mm thick.
11 parts, built around the TC33X-2-504E. 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 fgervais/project-ap63300-module repository on GitHub, at the commit this page was made from: the board is hardware/project-ap63300-module.kicad_pcb and its schematic hardware/project-ap63300-module.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 fgervais before reusing the design.
