31 parts, built around the CH340C, ESP-12E, AMS1086CD-3.3 and TYPE-C-31-M-12. 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 SparkMakerspace/certification-board repository on GitHub, at the commit this page was made from: the board is certification-board.kicad_pcb and its schematic certification-board.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 SparkMakerspace before reusing the design.
