SG90 Micro Servo Motor | 180° Rotation
The world’s most popular micro servo for hobbyists and students. Lightweight, affordable, and incredibly easy to control, the SG90 is the go-to choice for small-scale robotics, camera gimbals, and Arduino-based automation projects. Quality assured by Pro Tronix.
Product Overview
The SG90 Micro Servo from Pro Tronix is a tiny but mighty actuator that has become a staple in the maker community. Weighing only 9 grams, it packs enough punch to move small linkages, open latches, or rotate sensors.
Because it operates on a standard 180-degree rotation, you can precisely control its position to any angle between 0 and 180 degrees using PWM (Pulse Width Modulation). It is designed to work perfectly with the 5V output of an Arduino, ESP32, or Raspberry Pi, making it the ideal entry point for anyone learning about motion control and robotics.
