1/2/4/5/10PCS SG90 Servo Motor Micro RC 9G Robot Helicopter Airplane Car Boat

About this deal

The SG90 is one of the most popular micro servo motors for hobbyists and makers. It is a small, low-cost servo motor that can rotate 180 degrees with a maximum torque of 1.8 kg-cm, operates at 4.8-6V, and weighs approximately 9 grams, making it ideal for small-scale robotics and model control applications. Dimensions are approximately 22.2 x 11.8 x 31 mm. It is a good choice for beginners who want to make things move without building a motor controller from scratch, and each unit comes with three horns (arms) and hardware. The SG90 uses Pulse Width Modulation (PWM) for precise rotation control. It is compatible with all kinds of RC cars and electronics projects, including Arduino and Raspberry Pi, and works with JR and Futaba interfaces. Common uses include actuators in robots such as bipeds, hexapods, and robotic arms, as well as steering systems in RC toys. Buying in a multipack of up to 10 units makes it practical and economical for larger builds or to keep spares to hand.
