Detailed Description
The Dexter Industries NXTBee sensor brings the Digi XBee radios to the Lego Mindstorms NXT system! These high-speed long-distance wireless communications sensors allow your NXT to communicate with any other device with an XBee radio. The XBee 802.15 communication protocol is the standard for robots everywhere!
Communicate Far: With the NXTBee you can send information up to 300 ft and the NXTBee PRO up to 1.2 km.
Communicate Fast: The NXTBee utilizes the high speed RS-485 line for high speed communication.
Communicate Wide: The NXTBee uses the XBee protocol which includes point to point networking and mesh networking.
