The SG90 Micro Servo Motor – 9g Mini Servo with High Torque is a compact and highly versatile actuator designed for remote control (RC), robotics, and embedded electronics projects. Its lightweight 9g form factor, combined with remarkable torque and precise PWM control, makes it one of the most popular and cost-effective micro servos used by hobbyists, students, and professionals alike.

Operating on a standard 4.8V to 6.0V DC supply, the SG90 delivers responsive motion and smooth rotation over approximately 0° to 180°, making it ideal for steering mechanisms, pan/tilt camera mounts, robot joints, grippers, animatronics, and control surfaces. Its high torque (≈1.8 kg·cm at 6.0V) ensures reliable movement even under moderate mechanical load.

The servo is controlled via a PWM (Pulse Width Modulation) signal, which allows you to accurately set the desired angle with ease using microcontrollers such as Arduino, Raspberry Pi (via PWM driver), AVR, PIC, ARM, and DSP. The module includes servo horns and mounting screws, enabling secure installation in your project or robotic platform.

Popular across RC airplanes, cars, boats, educational robotics kits, and DIY automation projects, the SG90 micro servo is ideal for those seeking precise motion control in compact spaces without sacrificing performance. Its widespread compatibility and ease of use make it a staple component in makerspaces, classrooms, and prototype labs.
