functions, designed for efficient motion control. The product supports 6-16V DC power input (via \u003cstrong\u003eCAN\u003c\/strong\u003e interface) or 5V input (via Grove interface), and can automatically adjust the power coefficient to ensure optimal performance.\u003c\/p\u003e\n\u003cp\u003eIts built-in FOC closed-loop drive system uses a 3504 200KV brushless motor, with a maximum continuous phase current of 0.5A without forced cooling, and can reach 1A for short periods. The driver, with magnetic encoder feedback, supports current, speed, and position triple-loop control, ensuring precise control.\u003c\/p\u003e\n\u003cp\u003eAdditionally, the device features a 0.66-inch OLED display on the back for real-time status display. It also includes built-in 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUnit RollerCAN-Lite\u003c\/strong\u003e is fully open-source in both hardware and software, supporting motion control and parameter adjustment via \u003cstrong\u003eCAN\u003c\/strong\u003e or \u003cstrong\u003eI2C\u003c\/strong\u003e buses, and provides SWD and SWO debugging interfaces to further enhance developer flexibility. This product is used in robot joints, motion control, industrial automation, and visual demonstration projects.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\"
