PWM 1-2ms speed control knob.

It can be used to connect ESC signal lines to control brushless motors or underwater thrusters for operation.

If the ESC of the thruster/motor supports bidirectional, then the speed knob can control the thruster/motor to rotate clockwise or counterclockwise.
If the ESC of the thruster/motor supports only unidirectional, then it can only control one direction of rotation.
