First refer to the openplotter 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
