13Questions
How big is the Mux8 PCB?
It measures 17.8 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mux8 use?
13 parts, built around the PCF8574T and MAX14662ETI+. 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 Mux8 KiCad files?
From the greyltc/hardware repository on GitHub, at the commit this page was made from: the board is KiCAD/mux8/mux8.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mux8 design in my own project?
Its repository states no licence, so its author keeps all rights: ask greyltc before reusing the design.
