Description
MG90S Servo – 9g Micro Metal Gear Servo
The MG90S Servo is a compact 9g micro servo motor designed for precision motion control in robotics, RC models, and Arduino-based projects. Compared with standard plastic gear servos, the MG90S uses semi-metal reinforced gears, offering improved durability and torque stability under load.
This MG90S micro servo is available in multiple configurations:
- 180° Positioning Version – Accurate angle control for robotic joints, steering systems, pan-tilt cameras, and educational robotics.
- 360° Continuous Rotation Version – Full rotation speed control via PWM, suitable for mobile robots, wheels, and automation systems.
- Semi-Metal Gear Version – Balanced durability and cost performance, ideal for general-purpose engineering projects.

FAQ
Q1: Is MG90S better than SG90?
Yes. MG90S uses reinforced metal gears, making it more durable under load.
Q2: Can it be used with Arduino?
Yes. It works directly with Arduino PWM control libraries.
Q3: Is 360° version position controllable?
No. 360° version is designed for continuous rotation only.
