23 parts, built around the LD1117V33, BC547A and SRD-12VDC-SL-C. 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 bou6/water_ctrl_hw repository on GitHub, at the commit this page was made from: the board is water_ctrl_hw.kicad_pcb and its schematic water_ctrl_hw.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 bou6 before reusing the design.
