The Slice of Radio is the worlds best value two way secure wireless serial data radio for the Raspberry Pi. It is very easy to use because it sends and recieves via the standard onboard Pi serial port, this means you don't need any special software or drivers. Simply configure the serial port and you are good to go.

Comes as a pre built module, which is plug and play. The Slice of Radio is low profile and will fit inside many Pi cases, the Stealth and Pi-Bow have been tried already. The on board "chip" antenna gives good performance for a very small package and can be extended in range by simply soldering on an 8.2cm wire whip. For even greater range it is possible to a u.fl connector to provide an external connection to an antenna using an SMA to u.fl pigtail lead.

Specifications:

Plug n Play (uses the Pi serial port, requires no special software or drivers)
Long range (up to 100m line of sight with chip antenna, up to 500m with an external antenna)
Talk to any of our radios (communicate with the XRF, SRF, URF, ERF etc )
LED indicators for send and recieve (visually see what is happening)
Perfect choice to use LLAP sensors (talk directly to our sensors)
Code compatible with the popular Slice of Pi (the web is a great source of projects)
Supports 128bit AES encryption (scramble your data from peering eyes)
Supports wireless programming of the XinoRF and RFu direct from the Arduino IDE (build and program sensors and actuators direct from your Pi)
