TowerPro SG90 9g Micro Servo Motor (180°)

TowerPro SG90 9g Micro Servo Motor (180° Rotation)

The SG90 is a compact 9-gram micro servo motor and one of the most widely used actuators in hobby electronics. It rotates through roughly 180° and is controlled with a standard PWM signal, so you can set its angle directly from an Arduino, ESP32, Raspberry Pi or any microcontroller. Lightweight yet capable, it is perfect for robotics, RC models, camera pan/tilt mounts and countless DIY builds.

Frequently Asked Questions

How do I control it?
With a standard 50Hz PWM signal — most microcontrollers have a servo library that makes this easy.

What is its rotation range?
Approximately 180 degrees.

What voltage does it use?
4.8–6V. When driving several servos, use a separate power supply rather than the board’s 5V pin.
