The SG90 is a lightweight, high-quality, and cost-effective micro servo motor capable of rotating approximately 180 degrees (90 degrees in each direction). It is easy to control using standard PWM signals and servo libraries, making it a staple for educational STEM labs. It is widely used for building multi-axis robotic arms, steering mechanisms for obstacle-avoiding rovers, panning sensors, and IoT automation projects. It is fully compatible with microcontrollers like Arduino, ESP32, ESP8266, Raspberry Pi, and external drivers like the PCA9685.
