51 parts, built around the STM32WB55CEU6, DLF162500LT-5028A1, MIC5365-3.3YD5-TR and USBLC6-2SC6. 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 justinfederico/STM32testPCB repository on GitHub, at the commit this page was made from: the board is STM32WB/stm32mc.kicad_pcb and its schematic STM32WB/stm32mc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask justinfederico before reusing the design.
