58 parts, built around the ESP32-WROOM-32U and BSS138. 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 KocurMaros/MicroMouse repository on GitHub, at the commit this page was made from: the board is PCB/main_board/main_board.kicad_pcb and its schematic PCB/main_board/MCU.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 KocurMaros before reusing the design.
