Questions
How big is the Onstep PCB?
It measures 120 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Onstep use?
137 parts, built around the STM32F103C8T6, TMC2130-LA, DS3231S# and STPS5L60S. 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 Onstep KiCad files?
From the andshn/OnStep_STM32_PCB repository on GitHub, at the commit this page was made from: the board is onstep_pcb/onstep.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Onstep design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
