The Bluetooth Transceiver HC-05 TTL Module (With EN Pin)) Breakout is the latest Bluetooth wireless serial cable! This version of the popular Bluetooth uses the HC-05/HC-06 module. These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target.
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 Arduino 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. And now, we provide HC-05/06, HC-05 could be set to Master or Slave by a user. HC-06 just be Master or Slave, that could be customized.
