72 parts, built around the BMP390, ICM-42670-P and B120-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 vaishnav-ece/STM32-FixedWing-FlightController repository on GitHub, at the commit this page was made from: the board is flight control_uav.kicad_pcb and its schematic BMI_BHI.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).
