Questions
What parts does the StepperMotorDriver use?
17 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 StepperMotorDriver KiCad files?
From the Aryan-G4/NanoStep repository on GitHub, at the commit this page was made from: the board is StepperMotorDriver/StepperMotorDriver.kicad_pcb and its schematic StepperMotorDriver/StepperMotorDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StepperMotorDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aryan-G4 before reusing the design.
