53 parts, built around the DRV8871DDA, W25Q32JVSSIQ, BSS138DW-7-F-ES and ICM-20948. 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 LtBrain/aero repository on GitHub, at the commit this page was made from: the board is hardware/aero/aero.kicad_pcb and its schematic hardware/aero/aero.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
