MG90 MG90S Metal Gear Micro Servo

The MG90 MG90S Metal Gear Micro Servo is a small servo motor with metal gears, about the same size as the popular SG90 but stronger and more durable. It is controlled with a standard 50 Hz PWM signal over a 3-wire lead, so it works with the Arduino Servo library, the ESP32 and servo driver boards. It suits robots, RC models and STEM projects where plastic gears wear out or strip too easily.

MG90 MG90S Metal Gear Micro Servo Applications

• Small robots and robotics kits
• RC planes, cars and boats
• Animatronics and moving models
• Replacing SG90 servos where metal gears are needed
• Arduino and ESP32 robotics classes

What's in the Box

• 1 × MG90S metal gear micro servo

Tip: Power the servo from a separate 5 V supply rather than the Arduino 5 V pin, especially when using more than one, and connect the supply ground to the Arduino ground. It fits the same mounts as the SG90, including SG90/MG90S pan-tilt brackets.
