Questions
How big is the Stepper analyzer PCB?
It measures 102 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stepper analyzer use?
23 parts, built around the ACS70331EOLCTR-2P5B3 and AO3400A. 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 Stepper analyzer KiCad files?
From the zapta/simple_stepper_motor_analyzer repository on GitHub, at the commit this page was made from: the board is kicad/stepper_analyzer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepper analyzer design in my own project?
Its repository states no licence, so its author keeps all rights: ask zapta before reusing the design.
