Description
Roller485 Lite Unit is an integrated brushless DC motor motion control kit designed for efficient motion control. It supports 6-16V DC power input (via PWR485 interface) or 5V input (via Grove interface) and can automatically adjust power coefficients to ensure optimal performance. It features a built-in FOC closed-loop drive system, utilizing a 3504 200KV brushless motor. Without forced cooling, it can operate with a maximum continuous phase current of 0.5A and a short-term current of 1A. The driver uses a magnetic encoder for feedback and supports current, speed, and position control, ensuring precise control.
Additionally, the device is equipped with a 0.66-inch OLED display on the back to display the device's status in real-time. It also includes an RGB indicator light and function button for easy human-computer interaction. The product's base is designed with LEGO-compatible mounting holes and M3 screw holes, making it easy to assemble and integrate. Roller485 Unit’s hardware and software are fully open-source, supporting motion control and parameter adjustment through RS485 or I2C buses. It also offers SWD and SWO debugging interfaces, providing developers with greater flexibility. This product is widely used in robotic joints, motion control, industrial automation, and visual demonstration projects.
