CANBUS Stepper

Daisy Chain-able Closed Loop Stepper motor driver and controller. Click here for the Datasheet 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. A web GUI allows easy configuration and debugging of a whole system over a single USB connection to any node.
