51 parts, built around the ESP32-WROOM-32E, ADS1115IDGS, BME280 and CH340K. 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 schoolllex/ESPBoosted repository on GitHub, at the commit this page was made from: the board is ESPBoosted.kicad_pcb and its schematic ESPBoosted.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 schoolllex before reusing the design.
