SG90 9g Micro Servo Motor 180 Degree

The SG90 is the reference micro servo nearly every hobbyist encounters first: a 9 gram unit delivering 1.2 to 1.6 kg-cm of torque across a 3V to 7.2V range, light and small enough to go into projects where a full-size servo would be absurdly oversized - a control surface on a small foam plane, a light robotic gripper, a pan-tilt camera mount. Glass fiber gears keep the cost down compared to metal-gear alternatives, trading maximum durability for a price point that makes experimenting cheap.

Standard PWM servo control means it works with any flight controller, receiver or Arduino servo library already written for hobby servos, and the JR-style plug fits the connector standard most RC and Arduino servo headers already expect.

Common uses are lightweight robotics actuators, RC aircraft control surfaces, and pan-tilt camera or sensor mounts - any application where light weight and low cost matter more than maximum torque or metal-gear durability.
