This is a complete XBee wireless communication kit with everything you need to get up and running quickly, including 2 1mW XBee modules with wire antenna, the popular USB XBee Explorer, an XBee shield as well as headers required for the XBee shield.
The very popular 2.4GHz XBee modules from Digi (formally Maxstream) take the 802.15.4 stack (the basis for Zigbee) and wrap it into a very simple to use serial command set. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
The goal for this complete XBee Kit is to make wireless communication simple. Connect one XBee to the shield and your Arduino, connect the other XBee to the Explorer board and your computer, and you'll be able to seamlessly pass serial data to and from your Arduino wirelessly! Using this connection, you can transmit remote sensor data, or send data from your computer to update a scoreboard, or drive a robot from your keyboard!
The XBee Shield mates directly with an Arduino board, and equips it with wireless communication capabilities using the popular XBee module.
The serial pins (DIN and DOUT) of the XBee are connected through a SPDT switch, which allows you to select a connection to either the UART pins (D0, D1) or any digital pins on the Arduino (D2 and D3 default). Power is taken from the 5V pin of the Arduino and regulated on-board to 3.3VDC before being supplied to the XBee. The shield also takes care of level shifting on the DIN pin of the XBee.
The board also includes LEDs to indicate power and activity on DIN, DOUT, RSSI, and DIO5 pins of the XBee. The Arduino's reset button is brought out on the shield, and a 12x11 grid of 0.1" holes are available for prototyping.
This kit does not include a USB to Mini-B cable which is sold separately.
