TowerPro SG90 Micro Servo
This is a low cost plastic gear RC servo with 1.80kg.cm holding torque (at 4.8V). It is a perfect solution for student robotic projects who build arms or linkages. The advantage of RC servo over the DC brush motor is the ability to control its rotation angle.
Compatible with Arduino Servo library.
