Questions
How big is the Stepper Driver V1 PCB?
It measures 56.8 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stepper Driver V1 use?
74 parts, built around the CH340C, ESP32-WROOM-32D, XL1509-3.3E1 and TMC2226-SA-T. 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 Driver V1 KiCad files?
From the MATT-ER-HORN/Stepper-Driver repository on GitHub, at the commit this page was made from: the board is Stepper Driver V1.kicad_pcb and its schematic Stepper Driver V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepper Driver V1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
