MG90D Full Metal Servo – 360 Degree Continuous Rotation 

Micro size servo with 360 degree continuous rotation which is perfect for driving micro-robot drive wheels.

Unlike normal servos that can be commanded to an exact position within a range of about 180 or 360 degrees, these servos will rotate continuously in either direction with no ability to position it to a particular position.
Think of them more like small DC motors with a motor controller built-in that powers the motor and that allows you to start/stop and control direction.
The gears are metal, and the speed of rotation is controlled by the rate of PWM.
These types of servos are handy for driving wheels on a micro-robot where space is limited or if you just want to spin something.

These are driven by a PWM signal.  
A pulse width of approximately 1500uS (PWM value of about 185) will cause the motor to stop.  
A higher PWM value over about 195 will rotate the motor in one direction while a lower PWM value under about 175 will cause the motor to rotate in the opposite direction.  
If the PWM value drops below about 500uSec (PWM value of 62), the motor will also stop due to insufficient drive.

Motor Connections
The built-in cable has a 3-pin female connector that is usually mated with a male header:
Brown = Ground
Red = 5V
Orange = PWM Signal
