Hardware: XBee Wireless Modules

Got a hold of my first XBee Wireless Modules last weekend. These are a small, low power, low bandwidth data radio that operates in the 2.4 GHz band. They have the robustness of a WiFi device, but smaller, slower and less power (one milliwatt). Ideal for sensor networks and non-critical control networks. XBee specs claim these can run for years on a single 9 volt battery. These can be integrated with the Arduino devices to provide data, command and control functions with no need to connect network wiring.



Details:

These modules take the 802.15.4 stack (the basis for Zigbee) and wrap it into a 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.

Features:
  • 3.3V @ 50mA
  • 250kbps Max data rate
  • 1mW output (+0dBm)
  • 300ft (100m) range
  • Built-in antenna
  • Fully FCC certified
  • 6 10-bit ADC input pins
  • 8 digital IO pins
  • 128-bit encryption
  • Local or over-air configuration
  • AT or API command set
