55 parts, built around the TPS5430DDA, TPS7A3301RGWT, TPS7A4700RGWR and MSAST32MAB5476MPNDT1. 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 dwmorrin/power-module-skiff repository on GitHub, at the commit this page was made from: the board is power-module-skiff.kicad_pcb and its schematic power-module-skiff.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 dwmorrin before reusing the design.
