Compact Daisy Chainable Closed Loop Stepper motor driver and controller.

Click here to visit the Web GUI

The CANBUS Stepper integrates all essential components required to drive a NEMA 17 stepper motor into a single compact board, with control handled over CAN bus. Its CAN-based interface, combined with high-current connectors, enables straightforward daisy chaining of multiple boards.

Built around the ESP32-S3 microcontroller, the design incorporates a TMC2209 stepper driver for quiet and precise motion, along with a 14-bit rotary position sensor to enable closed-loop feedback. It is optimised for scalable, multi-axis systems requiring compact integration, low-noise operation, and precise closed-loop control.

The web GUI allows easy configuration, control and debugging of a whole system over a single USB or WiFi connection to any node.

Make sure you pick up some interconnect cables to connect drives together.

Open source Software

All source code available on the project GitHub.

From the Web GUI or over USB/Serial/CAN. See the project GitHub for more information.
The included screws are best suited for a 34mm length Nema 17 stepper motor.
Yes, all firmware is open-source and available on the project GitHub.
The PD Stepper is powered with USB PD, making it the simplest option for single motors. The CANBUS Stepper uses a DC supply, CANBUS comms and high power connectors, making it ideal for controlling multiple motors at once. The CANBUS Stepper also has a higher resolution encoder (14 bits vs 12 bits).
