Questions
How big is the Relay control PCB?
It measures 84.4 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Relay control use?
34 parts, built around the BC548 and G5LE-14 DC12. 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 control KiCad files?
From the Awrelo/4-Channel-Relay-Control-Circuit repository on GitHub, at the commit this page was made from: the board is relay_control.kicad_pcb and its schematic relay_control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relay control design in my own project?
Its repository states no licence, so its author keeps all rights: ask Awrelo before reusing the design.
