Questions
How big is the Modulo rele PCB?
It measures 19 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Modulo rele use?
9 parts, built around the BC337. 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 Modulo rele KiCad files?
From the TaielST/Modulo_rele repository on GitHub, at the commit this page was made from: the board is Modulo_Rele/Modulo_Rele.kicad_pcb and its schematic Modulo_Rele/Modulo_Rele.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Modulo rele design in my own project?
Its repository states no licence, so its author keeps all rights: ask TaielST before reusing the design.
