StepperMotorControllerBoard: common questions

What microcontroller does the StepperMotorControllerBoard use?

The StepperMotorControllerBoard is built around the ATmega328PB-MU, from the AVR/Arduino family.

How big is the StepperMotorControllerBoard PCB?

The StepperMotorControllerBoard measures 39 × 39.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the StepperMotorControllerBoard?

37 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the StepperMotorControllerBoard design files?

From the Case-Rocket-Team/StepperMotorControllerBoard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the StepperMotorControllerBoard design in my own project?

The repository has no license, so all rights stay with Case-Rocket-Team. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the StepperMotorControllerBoard 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.
