47 parts, built around the STM32F103CBT6. 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 SL-RU/wmup_clock repository on GitHub, at the commit this page was made from: the board is sch/awaker.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask SL-RU before reusing the design.
