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
