If you have followed the instructions you will have come across a quite interesting section. The Kelboy has the possibility of connecting a modern joystick in your DIY. This joystick requires a few installation steps.
Once the part in which we are going to connect our joy has been identified, we must place it in the following way:
That blue plate must be bent inwards, help yourself with some tweezers, and place it in the connector with the TOP label under the 5v joystick connector (this connector is for those who want to solder a different model).

At that moment the calibration function will be enabled from the firmware. Just follow the messages on the screen and at the end of the process the joystick will be enabled.
