The SG90 Micro Servo Motor is a lightweight, high-quality actuator designed for precision control in compact electronics applications. Weighing just 9 grams, this mini servo motor delivers a powerful balance of torque, speed, and reliability, making it a staple component for hobbyists, students, and professional developers alike.Its primary purpose is to provide precise angular positioning—typically up to 180 degrees—allowing users to control mechanical movements with high accuracy. Whether you are building a custom walking robot, a remote-controlled (RC) airplane, a pan-tilt camera assembly, or an automated smart home valve, the SG90 offers the ideal mechanical muscle without adding unnecessary bulk to your project.Engineered with a durable translucent blue housing and lightweight nylon gears, this micro servo minimizes power consumption while maintaining optimal performance. It operates seamlessly on a standard 5V power supply, making it directly compatible with popular development platforms including Arduino, Raspberry Pi, ESP32, and standard RC receivers.The SG90 is incredibly user-friendly, featuring a standard 3-pin connector (Power, Ground, and Signal) that simplifies wiring. It comes complete with multiple interchangeable servo horns (arms) and mounting hardware to accommodate various mechanical linkages. Ideal for STEM educators, robotics enthusiasts, and DIY makers, the SG90 is the ultimate entry-level servo for turning digital code into physical motion.4.
