Questions
What parts does the Relay use?
11 parts, built around the BC547. 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 Relay KiCad files?
From the Ashlaiden/PCB repository on GitHub, at the commit this page was made from: the board is Relay/Relay.kicad_pcb and its schematic Relay/Relay.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relay design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
