The SG90 Micro Servo 180° is a compact and lightweight positional servo motor ideal for Arduino, ESP32, Raspberry Pi, and general hobby electronics projects. It provides smooth and precise angle control across a full 180 degree rotation, making it perfect for steering mechanisms, robotic arms, pan tilt mounts, and other applications requiring accurate positioning. Operating on a standard 4.8–6V power supply, the SG90 integrates easily with popular microcontroller platforms and PWM-based control systems. Widely used by both beginners and experienced makers, the SG90 offers reliable performance at an affordable price. If your project requires step-by-step setup, wiring diagrams, and example code, follow this SG90 servo Arduino guide to get started quickly. If your application requires continuous rotation instead of fixed angle movement, check out the SG90 Micro Servo 360°. For a stronger alternative with metal gears, consider the MG90S metal gear servo. A detailed comparison of these servos and the larger MG996R is available in the SG90, MG90S & MG996R servo comparison guide.
