Questions
How big is the Quad relay mux PCB?
It measures 42 × 157.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Quad relay mux use?
102 parts, built around the BD63573NUV-E2, FT234XD-R, NCP45525IMNTWG-H and TCA6424ARGJ. 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 Quad relay mux KiCad files?
From the azonenberg/misc-devboards repository on GitHub, at the commit this page was made from: the board is quad-relay-mux/quad-relay-mux.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quad relay mux design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
