|+||Rudder feedback is useful to prevent the drive motor from stalling. It also provides nmea output of the rudder angle which can be displayed in opencpn.|
|+||A typical rudder feedback sensor has 3 wires. These wires go to a potentiometer which changes resistance with rudder angle.|
|+||It is possible to use rudder feedback with only 2 wires. In this case, the correct resistor needs to be placed in series with the rudder indicator.|
|+||The resistors on the motor controller can be replaced depending on the resistance of the rudder feedback used. Typically a potentiometer from 1k to 20k resistance is used, but if the resistance is higher or lower, different resistor values are needed.|
|+||The rudder feedback can be calibrated using either openplotter interface, or pypilot plugin for opencpn.|
