69 parts, built around the DRV8833RTYR, TPS61030PWP, BQ24074RGTR and B5819W. 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 acalinp/Astropi-micro repository on GitHub, at the commit this page was made from: the board is 01_Hardware/AstroPiMicro.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 acalinp before reusing the design.
