M5Stack U182 Roller485 Units

M5Stack U182 Roller485 Units are brushless DC motor actuator kits for efficient motion control. The M5Stack U182 supports 6V_DC to 16V_DC input via the PWR485 interface or 5V via the Grove interface, automatically adjusting power for optimal performance. An internal FOC closed-loop drive system uses a 3504 200KV motor and handles up to 0.5A continuous current (1A peak). A magnetic encoder provides feedback for precise current, speed, and position control. The axle can optionally include a slip ring, allowing continuous 360° rotation while maintaining power and data transmission. An OLED display on the back shows real-time status, and RGB lights and buttons enable user interaction. LEGO-compatible and M3 screw holes allow for easy mounting. The Roller485 Unit is fully open-source, with control via RS485 or I²C buses and SWD/SWO debugging interfaces for added flexibility. It is ideal for robotic joints, motion control, industrial automation, and visual demonstrations.
