DFRobot Bluetooth Bee Module - BT 2.0 XBee-Form-Factor led voltage meter And of courseBuild Faster with the Bluetooth 2. 0 Bee Module For Arduino This DFRobot Bluetooth Bee Bluetooth wireless module adapts the XBEE design. It has a compact size, the pinout is compatible with XBEE which is suitable for all kinds of microcontrollers such as Arduino who have 3. 3V power out, also the module supports AT commands for parameter setting. (NOTE: You have to use an XBEE adapter for parameter setting. ) The Bluetooth Bee modules come with an
