45 parts, built around the ESP32-S3-MINI-1U-N8, W25Q128JVPIQ, BQ24074RGTR and ICM-42688-P. 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 AndreaColombo74/SAM repository on GitHub, at the commit this page was made from: the board is sam.kicad_pcb and its schematic sam.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 AndreaColombo74 before reusing the design.
