This servo motor is a micro size 180 degree analog servo with metal gears and robust construction. This motor works well for basic servo experimentation and can be used in applications where small size is a virtue and that don’t require a huge amount of torque, but they are still pretty strong. This servo motor is comprised of a DC motor, gears, a potentiometer to determine its position and a small electronic control board. By using the motor you can command it to go to a specific position. Because of this usual go-to motor can also be commanded when accurate positioning is needed, such as for turning the front wheels on an RC model for steering or pivoting a sensor to look around on a robotic vehicle. Package Includes: 1 MG90S Servo motor with attached 9.5″ control cable 3 arms/horns for various interface applications 3 screws for mounting arms to the servo and mounting the servo Features Very small micro size Fairly strong, can lift 3.75 lb positioned 1 cm from center of shaft 180 degree rotation Sturdy metal gears Analog drive
