81 parts, built around the STM32WB55RGV6, DLF162500LT-5028A1, W25N01GVZEIG and LM1117MP-3.3. 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 Karanami/MircoMouse repository on GitHub, at the commit this page was made from: the board is hardware/main board/MircoMouse.kicad_pcb and its schematic hardware/main board/MircoMouse.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 Karanami before reusing the design.
