Questions

How big is the Knobs 1x4 PCB?

It measures 95 × 23.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Knobs 1x4 use?

5 parts. 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 1x4 KiCad files?

From the Mo-MoS/controllers repository on GitHub, at the commit this page was made from: the board is s2/kicad/knobs_1x4/knobs_1x4/knobs_1x4.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 1x4 design in my own project?

Its repository states no licence, so its author keeps all rights: ask Mo-MoS before reusing the design.
