Questions
How big is the Stepper switch PCB?
It measures 28 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stepper switch use?
27 parts, built around the MMBF170LT1G. 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 Stepper switch KiCad files?
From the prusa3d/MK2mm_Stepper_switch repository on GitHub, at the commit this page was made from: the board is stepper-switch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepper switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask prusa3d before reusing the design.
