The SG90 micro servo motor is a compact, high-precision positional actuator restricted to a 0-to-90 degree operational range. Controlled via standard Pulse-Width Modulation (PWM) signals, it accurately holds designated angular positions against external mechanical resistance. The package includes positional control horns and mounting hardware for immediate installation into lightweight projects. It is extensively used in robotic arms, steering mechanisms for small RC vehicles, animated props, pan-tilt camera rigs, and automated latching mechanisms.
