Description:

The MG90S Mini Servo Motor is a high-performance, compact servo designed for applications that require precise angular movement, high torque, and reliable durability in a small form factor. Built with robust metal gears, this servo provides significantly improved longevity and mechanical strength over traditional plastic gear servos, making it a preferred choice for robotics and RC hobbyists alike.

Operating on a voltage range of 4.8V to 6.0V, the MG90S delivers a torque output of up to 2.2 kg·cm at 6V, allowing it to lift, rotate, or position medium-weight loads with ease. With a fast response time of 0.08 seconds per 60° at 6V, the servo is exceptionally responsive, supporting precise control in time-sensitive applications such as robotic joints, pan-tilt camera mounts, and automated mechanisms.

The motor features a coreless design, which reduces internal inertia and enables smoother and more efficient operation. Its 180-degree rotation range allows it to rotate from one extreme to the other, making it ideal for directional control and positional adjustments.

The MG90S comes pre-fitted with a 3-wire female connector for signal, power, and ground connections, compatible with virtually all major microcontroller boards, including Arduino, Raspberry Pi, ESP8266/ESP32, STM32, and more. Its compact size and lightweight build — only 13.4 grams — make it especially suitable for drones, miniature robots, animatronics, and other projects with strict space and weight constraints.

The servo is equipped with a ball bearing and high-quality metal gears, ensuring smooth operation, less noise, and increased load endurance. A minimal dead band of around 5μs enhances its precision by reducing positional jitter.

Whether you're building a robot arm, designing an interactive project, or adding steering to a small RC car, the MG90S offers a perfect blend of performance, durability, and affordability in a compact package.
