Questions
How big is the Knobs mux PCB?
It measures 67 × 23.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Knobs mux use?
5 parts, built around the 74HC4067PW. 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 Knobs mux KiCad files?
From the Mo-MoS/controllers repository on GitHub, at the commit this page was made from: the board is s2/kicad/knobs_mux/knobs_mux/knobs_mux.kicad_pcb and its schematic s2/kicad/analog_mux/analog_mux/analog_mux.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Knobs mux design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mo-MoS before reusing the design.
