The SG90 9g Mini Servo Motor is a small and versatile actuator widely used in robotics, RC vehicles, aircraft, and educational electronics projects. It is designed to provide accurate angular positioning using a standard PWM (Pulse Width Modulation) control signal.
This servo operates at 4.8V and delivers a maximum torque of 1.6 kg·cm, making it suitable for lightweight mechanical systems. The motor uses durable nylon gears that provide smooth and reliable operation while keeping the overall weight to only 9 grams.
The SG90 responds to control pulses with a period of approximately 20 ms (50 Hz). The pulse width determines the output angle, typically ranging from 0.5 ms to 2.5 ms, corresponding to positions between 0° and 180°. This simple control method allows the servo to be easily interfaced with microcontrollers such as Arduino, ESP32, STM32, and other development platforms.
Its compact dimensions and universal connector make it easy to integrate into a wide range of applications including robotic arms, line-following robots, RC airplanes, pan-tilt camera systems, and small automation projects.
