Since now on, it will be easy to provide your Arduino with Internet connectivity by using this shield. The shield sports a TCP/IP stack manager, in order to free up the Arduino from some basic tasks. It’s also essential to equip the board with a library, that communicates with the TCP/IP manager and makes it easier to program the Arduino and to let  it communicate with other computers via the Internet.

The hardware is essentially based on a radio element (MRF24WB0MA) and a MCW1001Aprocessor by Microchip. The power supply is 3.3V (using a voltage regulator from the 5V of Arduino) but the processor also bears TTL levels. The radio element has also an antenna wired on its base. The processor is connected to the radio element via SPI lines (SDO, SDI, SCK) and other control lines such as CS, INT, RST, HIBERNATE, WP.

This project comes in kit. Some components have to be soldered to the included PCB.
