Questions
How big is the Steppers PCB?
It measures 54 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Steppers use?
55 parts, built around the LM1117-3.3, AO3407, MM3Z3V6 and SP0502BAHTG. 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 Steppers KiCad files?
From the eddyem/mmpp repository on GitHub, at the commit this page was made from: the board is electronics/steppers.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Steppers design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
