Questions
How big is the 2ch relay append PCB?
It measures 114.3 × 219.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 2ch relay append use?
190 parts, built around the BC548. 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 2ch relay append KiCad files?
From the ExploreEmbedded/Two-Channel-Relay-Board-5V- repository on GitHub, at the commit this page was made from: the board is Design Files/2ch_relay-append.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 2ch relay append design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExploreEmbedded before reusing the design.
