149 parts, built around the ESP32-S3-WROOM-1-N8, SED5120, TXB0106PW and WS2812B. 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 devramsean0/train-locs-board repository on GitHub, at the commit this page was made from: the board is board/board.kicad_pcb and its schematic board/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 devramsean0 before reusing the design.
