SG90 Micro Servo -9g - 180° or 360° Rotation
Micro RC Servo for Experimenters - Arduino Compatible
The SG90 micro servo motor is a compact, lightweight, and reliable actuator commonly used in Arduino, robotics, and RC control projects. Weighing just 9 grams, the SG90 is ideal for applications where size, weight, and precision are critical.
Operating on a standard 4.8–6V supply, the SG90 provides approximately 180 degrees or a 360 degree option of controlled rotation using simple PWM signals from most microcontrollers. Internal plastic gearing and closed‑loop position feedback allow the servo to move accurately to a commanded angle and hold its position under light mechanical load.
This servo is widely used by hobbyists and educators for pan‑tilt camera mounts, small robotic arms, animatronics, model aircraft control surfaces, and general motion experiments. The SG90 is compatible with Arduino, Raspberry Pi (via PWM), ESP8266/ESP32, and most RC servo controllers.
With its low cost, minimal power requirements, and extensive community support, the SG90 micro servo is an excellent choice for beginners and experienced builders alike. It pairs well with external 5V power supplies when driving multiple servos or operating under higher load conditions.
The miniature servo comes complete with three interchangeable horns.
