Questions
What parts does the Control Board use?
35 parts, built around the ESP32-WROVER and BC817W. 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.
Where can I download the Control Board KiCad files?
From the madpilot/sprinkler-control repository on GitHub, at the commit this page was made from: the board is hardware/Control Board.kicad_pcb and its schematic hardware/Control Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask madpilot before reusing the design.
