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. We added 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.
To use BlueTooth bee-Standalone more convenient and make it more usefull,you'd better downloadBlueTooth bee-Standalone Eagle files.
Bottom-view:
PD4 - PD7 = Arduino IDE digital pins 4 - 7 (5,6 PWM)
PB0 , PB1 = Arduino IDE digital pins 8 , 9 (9 PWM)
PC0 - PC3 = Arduino IDE analog pins 0 - 3 (Note PC2 Disconnects the Bluetooth via a rising edge)
Bluetooth Bee-Standalone board is of 24mm x 36mm size.
Example : Use Bluetooth Bee-Standalone to control a Grove-LED with XBee carrier.
Connect Grove-Led and Bluetooth Bee-Standalone module to XBee carrier like this.
Write a program by Arduino-IDE to read informations from the Bluetooth Softserial port and identify to shut or turn on the LED.

Connect the XBee carrier to computer with USB-cable and uploading the program to ATMEGA168 on the Bluetooth Bee-Standalone.
Remove the USB-cable form XBee carrier and connect the 3.7-Voltage battery to XBee carrier like this.
Use another Bluetooth Bee connect to the Bluetooth Bee-Standalone.How to connect? You can refer to Bluetooth Bee.When you are connected,you can control the LED by another Bluetooth Bee.The LED will work when you send "ON" to Bluetooth Bee-Standalone and it will be off when you send "SH"(short for SHUT).
