Questions
How big is the Tortoise Relay-4up PCB?
It measures 48.3 × 48.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tortoise Relay-4up use?
20 parts, built around the EC2-12NU. 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 Tortoise Relay-4up KiCad files?
From the RandyStockberger/Tortoise-Relay repository on GitHub, at the commit this page was made from: the board is Tortoise-Relay-4up.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tortoise Relay-4up 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).
