Questions

What parts does the Luca Rele use?

246 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 Luca Rele KiCad files?

From the smatuu/comienzo-de-github repository on GitHub, at the commit this page was made from: the board is HARDWARE/Rele/Luca-Rele.kicad_pcb and its schematic HARDWARE/Rele/Luca-Rele.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Luca Rele design in my own project?

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