DFROBOT Gravity DC Micro Metal Gear Motor with Driver, 30:1 Reduction

The DFROBOT Gravity DC Micro Metal Gear Motor with Driver is a compact and versatile motion solution, combining the precision of a servo with the continuous rotation of a DC motor. Its integrated driver and 3-pin Gravity interface make it exceptionally easy to operate, requiring only a single control signal for complete command.

This motor features a robust 30:1 metal gear reduction, providing excellent torque for its size. You have full control over forward/reverse movement and speed via a simple PWM (Pulse Width Modulation) signal, allowing for precise speed adjustment and directional changes in your projects. It operates efficiently within a 3.5V to 8V range.

Key Specifications & Features

• Integrated Control: The onboard driver chip simplifies wiring and programming, consuming minimal static current (less than 1mA with no signal).
• Precise Signal Control: Utilises a 500Hz PWM frequency with a PPM signal resolution of 1µs for accurate speed and position control.
• Dedicated Pulse Ranges: Specific pulse width ranges define clockwise rotation (500µs-1400µs), stop (1400µs-1600µs), and anticlockwise rotation (1600µs-2500µs), with maximum speeds at the range extremes.
• Compact Metal Gearbox: The all-metal planetary gear train ensures durability and reliable torque transmission in a tiny footprint.

Ideal for a wide range of applications, from embedded systems and IoT devices to robotics and educational electronics projects. Please note: the embedded control chip causes a slight voltage drop, meaning the motor's actual operating voltage and top speed will be marginally lower than the input supply.
