Questions
How big is the UniversalStepperDriver PCB?
It measures 65 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UniversalStepperDriver use?
88 parts, built around the STM32F411RET6, MPQ4420GJ-Z and ULN2003V12D. 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 UniversalStepperDriver KiCad files?
From the IRNAS/Universal-Stepper-Driver-Rpi repository on GitHub, at the commit this page was made from: the board is UniversalStepperDriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UniversalStepperDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask IRNAS before reusing the design.
