79 parts, built around the ATTINY3224-SSU, IR2104SPBF, SS34 and SUD50N03-06AP-E3. 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 Siddharth2308/esc repository on GitHub, at the commit this page was made from: the board is project_files/diy_esc.kicad_pcb and its schematic project_files/diy_esc.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 Siddharth2308 before reusing the design.
