Questions
How big is the StepperDriver PCB?
It measures 12 × 27.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the StepperDriver use?
20 parts, built around the ATTINY13A-SSU, LTV-357T and BAT54CW. 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 StepperDriver KiCad files?
From the bask185/microStepper repository on GitHub, at the commit this page was made from: the board is stepperDriver/PCB/stepperDriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the StepperDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask bask185 before reusing the design.
