This option allows you to enable support for the radio module Pi433.
Pi433 is a shield that fits onto the GPIO header of a Raspberry Pi
or compatible. It extends the Raspberry Pi with the option, to
send and receive data in the 433MHz ISM band - for example to
communicate between two systems without using ethernet or bluetooth
or for control or read sockets, actors, sensors, widely available
for low price.
