SG90 Micro Servo Motor 180° 1.8 kg.cm Plastic Gears – Compact & Reliable Performance

The SG90 Micro Servo Motor is one of the most popular and widely used servo motors in robotics, automation, and DIY electronics projects. Known for its compact size, lightweight build, and reliable performance, this servo is an essential component for students, hobbyists, engineers, and makers who want precise control over movement. With its 180° rotation, 1.8 kg.cm torque capacity, and durable plastic gears, the SG90 is ideal for applications where size and efficiency matter most.

Compact Design with Powerful Performance

Despite its small size, the SG90 Micro Servo Motor delivers impressive torque of 1.8 kg.cm at 4.8V, making it suitable for lightweight robotics, RC models, and automation systems. Its 180° rotation angle provides smooth and precise movement control, which is critical in projects that require accuracy, such as robotic arms, pan-tilt camera systems, or sensor positioning mechanisms.

The servo weighs only around 9 grams, making it ultra-lightweight and easy to integrate into projects where every gram counts. Its compact dimensions (22.2mm x 11.8mm x 31mm) allow it to fit in tight spaces while still offering reliable performance.

Durable Plastic Gear Construction

The SG90 Micro Servo Motor is built with plastic gears that ensure smooth operation while keeping the servo lightweight. The plastic gear system is engineered to provide a balance between cost-efficiency and durability. While not as strong as metal gears, plastic gears are more than sufficient for most light to medium-duty applications, making this servo motor an affordable choice for a wide range of projects.

Easy Control and Wide Compatibility

The SG90 Micro Servo Motor is controlled using PWM (Pulse Width Modulation) signals, making it compatible with most popular microcontrollers, including Arduino, Raspberry Pi, ESP32, and STM32 boards. Its 3-wire connector (Ground, Power, and Signal) makes wiring simple and straightforward.

This servo typically operates at 4.8V to 6V, making it suitable for direct use with batteries, power supplies, or development boards. Whether you are building a line-following robot, a pan-tilt camera mount, or a simple automated system, the SG90 is designed for seamless integration.
