Questions

What parts does the LightSwitchShield use?

8 parts, built around the ARDUINO UNO R3 and BC328. 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 LightSwitchShield KiCad files?

From the The-Hemogoblin/Projects repository on GitHub, at the commit this page was made from: the board is IR-LightSwitch/KiCAD/LightSwitchShield.kicad_pcb and its schematic Cable-Tester/CableTester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the LightSwitchShield design in my own project?

Its repository states no licence, so its author keeps all rights: ask The-Hemogoblin before reusing the design.
