The SG90 Micro Servo Motor (9g) is a compact and lightweight servo motor widely used in Arduino, robotics, and STEM projects. It provides precise angular control (0–180°) using PWM signals, making it ideal for small robotic arms, steering mechanisms, pan-tilt camera mounts, and automation projects.

With low power consumption and easy interfacing, the SG90 is perfect for beginners, students, and makers working on DIY electronics and educational robotics.
