Description
Unit Roller485-Lite is a brushless DC motor motion execution kit with integrated control functions, designed for efficient motion control. The product supports 6-16V DC power input (via the PWR485 interface) or 5V input (via the Grove interface), and can automatically adjust the power coefficient to ensure optimal performance. It features a built-in FOC closed-loop drive system, using a 3504 200KV brushless motor, with a maximum continuous phase current of 0.5A and a short-term current of 1A without forced cooling. The driver uses a magnetic encoder as feedback, supporting current, speed, and position triple-loop control to ensure precise control.
Additionally, the device is equipped with a 0.66-inch OLED display on the back to show real-time device status, and includes RGB indicators and function buttons for easy human-machine interaction. The product base is designed with LEGO-compatible mounting holes and M3 screw holes for quick assembly and integration. The Unit Roller485-Lite is fully open-source in both hardware and software, supporting motion control and parameter adjustment via RS485 or I2C buses, and provides SWD and SWO debugging interfaces to further enhance developer flexibility. This product is used in robotic joints, motion control, industrial automation, and visual demonstration projects.
