                    The Bluetooth Transreceiver HC-05 Breakout is the latest Bluetooth wireless serial cable! This version of the popular Bluetooth uses the HC-05/HC-06 module.

                  The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit or Arduio XBee USB Adapter if you need to attach this to a computer. You can either solder a 6-pin header or individual wires. Unit comes without a connector. Please see related male and female pins below.
