Stepper driver: common questions

What microcontroller does the Stepper driver use?

The Stepper driver is built around the ATXMEGA128A1U-AU, from the AVR/Arduino family.

How big is the Stepper driver PCB?

The Stepper driver measures 124.4 × 80.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Stepper driver?

207 components, from 52 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Stepper driver design files?

From the harp-tech/device.stepperdriver repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Stepper driver design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Stepper driver without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
