Servo module is built on top of PWM module and allows user to define angles instead of duty_cyles to control a PWM enabled servo motor like SG90. When the button is pressed the servo motor moves to an angle defined by `angle_push` and when button is released it moves back to `angle_release`. In the example configuration for a [cheap 5V SG90 Servo](https://www.ebay.co.uk/itm/184555802744), the motor moves to an angle of 45 degrees when button is pressed and moves back to 20 degress when released.

To use Servo motors in PiKVM you need to follow steps 1-3 for [PWM Module](#pwm) and then use the following configuration. To use Servo motors in PiKVM you need to follow steps 1-3 for [PWM Module](#pwm) and then use the following configuration.
