Save that extra Arduino you have lying around for another project, this two-for-one device has the Arduino built-in. Bluetooth Bee with Arduino is an enhanced version of the Bluetooth Bee. There is an onboard ATMEGA168 to it to make it a full-featured Arduino while maintaining the same footprint and instruction set as the Bluetooth Bee. Plus, it still allows you to stack it on XBee Carrier, XBee® Shield, and UartSBee for expansion or reprogramming
