Questions
How big is the Relais M PCB?
It measures 60 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Relais M use?
13 parts, built around the ATTINY25-20PU, BC557 and RT314A05. 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 Relais M KiCad files?
From the REcassy/Relais-M repository on GitHub, at the commit this page was made from: the board is Relais-M.kicad_pcb and its schematic Relais-M.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relais M design in my own project?
Its repository states no licence, so its author keeps all rights: ask REcassy before reusing the design.
