Questions
What parts does the Cat feeding machine use?
11 parts. 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 Cat feeding machine KiCad files?
From the CharleezGithub/IoT-Project-Feeder repository on GitHub, at the commit this page was made from: the board is cat feeding machine/cat feeding machine.kicad_pcb and its schematic cat feeding machine/cat feeding machine.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cat feeding machine design in my own project?
Its repository states no licence, so its author keeps all rights: ask CharleezGithub before reusing the design.
