Price: 39.50 - 47.40 (2 variants)

The RollerCAN Unit is a brushless DC motor motion control kit that supports 6-16V DC input via the CAN (XT30) interface or 5V input through the Grove connection, with automatic power factor adjustment for optimal performance. Its FOC closed-loop drive system uses a 3504 200KV brushless motor, delivering a continuous phase current of up to 0.5A without forced cooling and 1A for short bursts. Feedback from a magnetic encoder gives you precise control of current, speed, and position.

There is an optional slip ring on the shaft, providing a continuous 360° rotation while keeping the Grove connection connected between the top and base. This allows for power and data transmission through the rotating part and makes it easy to expand with additional modules. The slip ring also provides an extra I2C Connector.

A 0.66" OLED display on the back provides real-time status updates, and the RGB indicator and function button makes interaction with it simple. The top and base include LEGO-compatible mounting holes and M3 screw holes, making it easy to assemble and incorporate into builds. The hardware and software are open-source, supporting motion control and parameter adjustments via CAN or I2C buses, and providing SWD and SWO debugging interfaces for developers.

There are two versions of this unit. Unit Only and with Slip Ring. Please choose which option you want before adding to the cart!
