First refer to the openplotter [[https://docs.sailoog.com/openplotter-v1-x-x/|Documentation]] to get a working openplotter system.


You will need:

  * [[inertial sensors]] - accelerometer, gyro, compass  connected over either I2C or SPI
  * [[motor controller]] - connected over tx/rx pins, or usb serial port
  * [[rudder drive motor]] - electric motor to move the rudder
  * raspberry pi running openplotter,

See [[troubleshooting]] if the autopilot fails to work from the openplotter menu
