The Tower Pro SG90 9g Servo Motor is one of the most popular 9g servo in the world.

The Tower Pro SG90 9g Servo motor is 180° rotation servo. It is a Digital Servo Motor which receives and processes PWM signals faster. It equips sophisticated internal circuitry that provides good torque, holding power, and faster updates in response to external forces.This servo motor is an excellent choice for various Arduino projects and is the same servo that we use in some of our Arduino courses.
