157 parts, built around the STM32G431C6T6, AP63205WU, INA4180A4IPW and BAT54S. 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 gabtie/ESC_24V repository on GitHub, at the commit this page was made from: the board is esc.kicad_pcb and its schematic control unit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
