StepperChecker

StepperChecker is a stepper motor driver dev and test board, designed to be easy to build, setup, and use. It will take any stepstick style motor driver and any Feather compatible microcontroller board. The basic intent is to have firmware loaded that will move the motor forward or reverse based on which button is pressed, at a sped defined by the potentiometer. But, of course, the sky is the limit given the many Feather boards available.

Questions

How big is the StepperChecker PCB?

It measures 89.4 × 69.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the StepperChecker use?

34 parts, built around the R-78E5.0-1.0 and PJ-202AH. 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 StepperChecker KiCad files?

From the adammhaile/StepperChecker repository on GitHub, at the commit this page was made from: the board is StepperChecker/StepperChecker.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the StepperChecker design in my own project?

Its repository states no licence, so its author keeps all rights: ask adammhaile before reusing the design.
