43 parts, built around the FUSB302BMPX and BD33C0AFP-CE2. 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 SK-Electronics-Consulting/battery-simulator repository on GitHub, at the commit this page was made from: the board is PCB/battery simulator PCB.kicad_pcb and its schematic PCB/Power Input.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 SK-Electronics-Consulting before reusing the design.
