Gear Micro Servo Motor For robot Plane Helicopter Boat Car Horns servo Remote controlled aircraft for DIY.

The model is suitable for ordinary small electric aircraft models and is not recommended in large fixed wing and electric helicopter.

The use of superior waterproof ABC hard shell.

Connections:

Pin-1 (Brown):   GND 
Pin-2 (Red):      +5V

Pin-3 (Orange): PWM

Driving PWM:

The PWM signal produced should have a frequency of 50Hz ( period should be 20ms).
Out of which the On-Time can vary from 1ms to 2ms.

So when the on-time is 1ms the motor will be in 0° and when 1.5ms the motor will be 90°.
Similarly when it is 2ms it will be 180°.
So, by varying the on-time from 1ms to 2ms the position can be controlled from 0° to 180°.
