About the Stepper impulse PCB

Stepper impulse is an open source PCB design by bastien-sagetat, published on GitHub. It is a 2-layer board measuring 55 × 55 mm, with 8 components from 5 distinct parts.

Other key parts include the TMC2208 and NUCLEO-G431KB. By type, the board carries 3 ICs, 3 connectors and 2 capacitors.

It belongs with the robotics & motion designs in this gallery.

From the project

Stepper motor controller

stepper-impulse is a controller for up to two stepper motors, allowing speed and position control through commands received via its serial port.

- firmware/: Contains the STM32 project files for the software implementation: source code, cmake files, STM32CubeMx project files. - hardware/: Contains the Kicad project files for the PCB design: Schematic, PCB layout, gerbers, symbols, footprints. - doc/: Contains extra documentation and resources (e.g.: images). - tools/: Contains tool scripts (mostly Python scripts).

Stepper impulse: common questions

How big is the Stepper impulse PCB?

The Stepper impulse measures 55 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stepper impulse?

8 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stepper impulse design files?

From the bastien-sagetat/stepper-impulse repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

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

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