This is the Xbee Explorer Dongle unit for the XBee line.
Better than XBee at a comparable cost! This module features the powerful ATmega128RFA1, transmitting on 2.4GHz with OTA (Over-The-Air) speeds up to 2Mbps, maximum 4.8km (3 miles) range and switchable internal /external antenna.
These infrared photodiodes are a proven light sensor in BEAM technology.
The is a breakout board for the popular XBee modules. Board includes easy-to-sew tabs and all the necessary power regulation to run on the LilyPad system.
This board mates directly with the Arduino USB board and allows the Arduino to wirelessly communicate over a modified ZigBee protocol using the popular XBee module from MaxStream.
