* '''G0''': This is the GPIO 0 pin of the radio module. This pin has a special interruption function attached to it because it act as '''IRQ''' (Interrupt Request) pin. The radio module manipulate it to send to notification toward the micro controller. This pin is in 3.3V logic. | * '''G0''': This is the GPIO 0 pin of the radio module.
