Description

RollerCAN Unit is a brushless DC motor motion control kit with multiple integrated control functions, designed for efficient motion control. It supports 6-16V DC power input (via the CAN (XT30) interface) or 5V input (via the Grove interface) and can automatically adjust the power factor to ensure optimal performance. It features a built-in FOC closed-loop drive system, using a 3504 200KV brushless motor. The maximum continuous operating phase current is 0.5A without forced cooling, and 1A for short-term. The driver uses a magnetic encoder for feedback and supports current, speed, and position triple-loop control, ensuring precise control. The unit’s shaft can optionally include a slip ring, allowing the Grove interface on the top to remain connected with the bottom, supporting 360° rotation while expanding additional modules at the top. This ensures power and data transmission through the rotating part.

Additionally, the unit is equipped with a 0.66-inch OLED display on the back, which can display the device status in real-time. It also includes an RGB indicator and function button for easy human-machine interaction. The top and base are designed with LEGO-compatible mounting holes and M3 screw holes, making it easy to build and integrate quickly. RollerCAN Unit's hardware and software are fully open-source, supporting motion control and parameter adjustment via CAN or I2C buses, and it also provides SWD and SWO debugging interfaces, offering developers greater flexibility. This product is widely used in machine joints, motion control, industrial automation, and visual demonstration projects.
