The XBee Pro series borrows from the excellent “Series 1” units, but now offers a schwackload of range! These 2.4GHz communication modules also take the the 802.15.4 stack and wrap it with a tasty, easy-to-use serial interface command set.

This particular model is the “XBee-PRO 802.15.4″ (formerly Series 1) part XBP24-ACW-001, and features:

• 63 mW built-in mini wire whip antenna
• 63 mW output (but the chip antenna designation kinda gives that away already, huh?)
• 250kbps communication speed
• 3.3V @ 50mA power consumption
• 1.6kM (1 mile) range (line-of sight, which is pretty darn good!)
• 6 10-bit ADC input pins
• 8 digital I/O pins
• 128-bit encryption
• Uses standard AT or API command sets
• Industrial temperature rating (-40° C to 85° C), so feel free to use it in your hot-tub in Iceland.
• FCC certified for USA, Canada, Australia, & Europe. No worries about men in antenna-laden vans driving up to your house with a “you’ve been naughty” look on their faces.
