Questions
How big is the Stepper stick PCB?
It measures 20.8 × 15.7 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Stepper stick use?
18 parts, built around the A4988SETTR-T. 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 stick KiCad files?
From the lightside-instruments/stepper-stick repository on GitHub, at the commit this page was made from: the board is stepper-stick.kicad_pcb and its schematic stepper-stick.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepper stick design in my own project?
Its repository states no licence, so its author keeps all rights: ask lightside-instruments before reusing the design.
