The SG90 Micro Servo Motor is a compact, lightweight, and highly reliable servo designed for robotics, RC models, automation systems, and embedded electronics projects. Weighing only 9 grams, this miniature servo delivers precise angular positioning through Pulse Width Modulation (PWM) control, making it ideal for Arduino, ESP32, Raspberry Pi, PIC, and other microcontroller-based applications.
Featuring durable nylon gears, low power consumption, and fast response times, the SG90 provides smooth and accurate movement over a rotation range of approximately 180 degrees. Its compact size and ease of integration have made it one of the most widely used servos among hobbyists, students, educators, and professional developers.
