423 parts, built around the ESP32-C3FH4, SN74LV1T34DBV, RT9080-TD 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 HekiNav/finland-live-train-map repository on GitHub, at the commit this page was made from: the board is pcb/fin-ltm.kicad_pcb and its schematic pcb/fin-ltm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
