Steering Gear Control:
The control of the steering gear generally requires a time base pulse of about 20ms, and the high level part of the pulse is generally the angle control pulse part in the range of 0.5ms~2.5ms.

1. Servo 0-180 Degree
The corresponding control relationship is as follows:
0.5ms---------------0 degrees;
1.0ms--------------45 degrees;
1.5ms--------------90 degrees;
2.0ms--------------135 degrees;
2.5ms--------------180 degrees

For 180 degree servo, please use a professional PWM Servo Controller to control the angle

2. Servo 360 Degree 
The steering gear is actually equivalent to a geared motor with infinitely variable speed, which can control the speed and direction of the rotation. There is no 0-360 degree angle control function.
