This is a NRF24L01plus shield with a special connector for this module. Have a look what is available in the shop.
It still retains the features of the normal prototype shield such as a power LED and a switcheable LED.
In addition there is a reset switch and a switch which can be connected to an input pin.
The module can be found http://arduino-projects4u.com/product/nrf24l01plus-module/
The Nordic nRF24L01plus is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. With peak RX/TX currents lower than 14mA, a sub μA power down mode, advanced power management, the nRF24L01plus provides a true ULP solution enabling very low power consumption for battery operated solutions. The Enhanced ShockBurst™ hardware protocol accelerator offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with the arduino.
The Nordic nRF24L01plus integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. No external loop filter, resonators, or VCO varactor diodes are required, only a low cost ±60ppm crystal, matching circuitry, and antenna.
There are quite some sites explaining how to use this module and it is even listed on the arduino playground here http://arduino.cc/playground/InterfacingWithHardware/Nrf24L01
Main functionality is to have two arduinos communicate with one another which is what most of the examples refer to.
With nthis version its simply a matter of plug and play. The NRF24L01plus module plugs into the shield and all the pins are connected through to the correct arduino pins.
