95 parts, built around the FD6288Q, AP2112K-3.3, SN74LVC1T45DBV and TJA1051TK/3/1. 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 VimDrones/AM32_esc_development_board repository on GitHub, at the commit this page was made from: the board is vimdrones_esc_development_board.kicad_pcb and its schematic vimdrones_esc_development_board.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).
