TowerPro SG90 Micro Servo Motor 9g – 180 Degree Rotation

Overview 

The TowerPro SG90 is a high-quality, low-cost micro servo that has become the gold standard for hobbyists and students. With its tiny footprint and high power-to-weight ratio, it is the go-to choice for moving robotic joints, controlling steering in RC cars, or adjusting flaps on RC aircraft. It features a standard 3-pin interface (PWM) and comes with a variety of “horns” (attachment arms) to fit any mechanical design.

Key Features 

• 180-Degree Precision: Moves exactly where you tell it to (between 0° and 180°) and stays there.

• Ultra-Lightweight: At only 9 grams, it won’t weigh down your micro-drones or foam-board planes.

• Microcontroller Ready: Works seamlessly with Arduino (using the Servo.h library), ESP32, and Raspberry Pi.

• Complete Kit: Includes 3 different plastic horns and mounting screws for immediate installation.
