M5Stack RollerCAN Lite Unit without Slip Ring (STM32)

The RollerCAN Lite Unit is a brushless DC motor motion control kit with multiple integrated control functions, designed to provide efficient motion control solutions for a range of applications. The device is compatible with both 6-16V DC power input (via the CAN interface) and 5V input (via the Grove interface), and is equipped with a power factor adjustment feature that ensures optimal performance. The product features a built-in FOC closed-loop drive system that utilizes a 3504 200KV brushless motor. The maximum continuous operating phase current is 0.5A without forced cooling and 1A for short-term operation. The driver employs a magnetic encoder for feedback and offers triple-loop control of current, speed, and position, thereby ensuring precise control.

Furthermore, the rear of the unit is furnished with a 0.66-inch OLED display, which provides real-time status information on the device. Furthermore, the product features an RGB indicator and function button, facilitating straightforward human-machine interaction. The base of the product is designed with LEGO-compatible mounting holes and M3 screw holes, allowing for quick assembly and integration. The hardware and software of the RollerCAN Unit are fully open-source, supporting motion control and parameter adjustments via the CAN or I2C bus, and offering SWD and SWO debugging interfaces to enhance developer flexibility. This product is widely used in machine joints, motion control, industrial automation, and visual demonstration projects.
