SG90 Servo

The SG90 Servo Motor is a miniature, high-performance actuator widely used in robotics, RC vehicles, and automation projects. Known for its compact size and lightweight design (9 grams), it provides precise angular control up to 180 degrees. This servo features a plastic gear train, making it suitable for low to medium torque applications. It operates on a voltage range of 4.8V to 6V, with a typical operating voltage of 5V, making it compatible with most microcontroller boards like Arduino. The SG90 consists of an electronic assembly, protective case, drive gears, and an output spline. It offers a stall torque of 1.2kg-cm at 4.8V and 1.6kg-cm at 6.6V, with an operating speed of 0.1s/60°. Common applications include robotic arm joints, pan-tilt camera mounts, and model aircraft control surfaces. Buyers should choose the SG90 for its affordability, ease of integration, and widespread community support. It is an excellent entry-level servo for hobbyists and students entering the world of mechatronics.
