Questions
How big is the Stepper PCB?
It measures 45 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stepper use?
34 parts, built around the STM8S105K4T6C, ULN2803A, AO3401 and SP0504BAHTG. 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 KiCad files?
From the eddyem/scorpio repository on GitHub, at the commit this page was made from: the board is kicad/stm8_platform/stepper.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepper 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).
