MG90S Micro Servo Motor 360° 2.2 kg.cm Metal Gears

The MG90S Micro Servo Continuous Rotation 360° (Full Metal Gear) is a compact and powerful servo motor designed for small-scale robotics and automation projects requiring continuous motion. Unlike standard servo motors that rotate only 180°, this version is modified to rotate freely in both directions, making it ideal for applications such as robotic wheels, camera sliders, conveyor systems, and pan-tilt mechanisms. Built with high-quality metal gears, the MG90S offers durability and wear resistance, ensuring a longer operational life compared to servos with plastic gears. Its full metal gear construction also allows it to handle more torque and stress without stripping or failing under moderate loads. Despite its small size, it provides sufficient torque for driving lightweight robotic platforms and other moving parts. The MG90S operates on a standard 4.8V to 6V power supply and is compatible with popular microcontrollers like Arduino, Raspberry Pi, and others through simple PWM (Pulse Width Modulation) signals. The direction and speed of rotation are controlled by varying the pulse width — typically, 1.5 ms stops the motor, pulses less than 1.5 ms rotate it in one direction, and pulses above 1.5 ms rotate it in the opposite direction. This servo comes with a standard 3-pin connector (Signal, VCC, GND) and is easy to integrate into a variety of electronics projects. Its compact form factor makes it especially suitable for space-constrained builds like mini-robots, remote-controlled toys, or animatronics. Overall, the MG90S 360° continuous rotation servo combines durability, versatility, and ease of use, making it an excellent choice for hobbyists, students, and developers looking to add controlled motion to their creations in a small package.
