Questions
How big is the SteppperMotorPCB PCB?
It measures 50.5 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SteppperMotorPCB use?
8 parts. 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 SteppperMotorPCB KiCad files?
From the Parathova/stepper-motor-controller-pcb repository on GitHub, at the commit this page was made from: the board is SteppperMotorPCB.kicad_pcb and its schematic SteppperMotorPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SteppperMotorPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Parathova before reusing the design.
