Questions
How big is the StepperControllerPCB PCB?
It measures 65 × 120 mm and has 4 copper layers, 1.6 mm thick.
What parts does the StepperControllerPCB use?
139 parts, built around the CH224K, DRV8818PWPR, EC12D1524403 and 1TS005F-2500-5001. 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 StepperControllerPCB KiCad files?
From the Hennnnnnryyyy/StepperController repository on GitHub, at the commit this page was made from: the board is PCB/KiCAD/StepperControllerPCB.kicad_pcb and its schematic PCB/KiCAD/Buttons.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StepperControllerPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hennnnnnryyyy before reusing the design.
