2 parts, built around the STM32L051C6T6. 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 ncsurobotics/SW9E-MicrocontrollerSpec repository on GitHub, at the commit this page was made from: the board is SW9-MCU_BOARD/SW9-MCU_BOARD.kicad_pcb and its schematic SW9-MCU_BOARD/SW9-MCU_BOARD.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).
