If you've ever looked into using Bluetooth in your projects, then you've probably come across the venerable HC-05 module before. It's probably the most commonly used Bluetooth module available because it provides a cheap, reliable TX/RX pipeline using the classic Bluetooth protocol. 

The HC-05 module itself is mounted onto a breakout board which provides easy, breadboard friendly 0.1" headers for Power, Ground, TX, RX, and enable pins. The breakout board also provides logic level shifting which allows the HC-05 to be compatible with the 5V logic levels of Arduino and other popular microcontroller boards. 

The HC-05 is designed to be a transparent TX/RX serial pipeline which allows devices to communicate over serial as they would through a wired connection. The is made possible by the Bluetooth software stack that is onboard the HC-05 module.

Getting started with the HC-05 is as easy as connecting it up to your microcontroller, configuring it using simple AT commands, and then pairing it with other Bluetooth devices.

**The HC-05 and HC-06 are 3.3V devices. They have a 5V regulator on board so you can power them with 5V, however, for communication and to use the KEY pin with a 5V board such as an Arduino Uno, you'll need a logic level converter such as this fantastic one from Sparkfun**

Some HC-05's come with an onboard button which is connected to pin34 of the HC-05 module to enter into AT command mode, whereas others have a pin broken out to the header. We've covered using both versions of the board in our Bluetooth tutorials below.

**Note that the HC-05 can be configured as either a Master or a Slave device, whereas it's brother, the HC-06, can only be used as a Slave device**

    Easy to use and connect your projects to your android phone. Also when it connects to my phone the connection speed drops to 9600 baud, it's probably a default android setting. And I received the device the next day after I ordered it so I'm happy there too. (Posted on 10/08/2017)

    After buying a faulty one off an auction site ,

    This time decided to buy locally no problems programming it with the Pi3 and running with a Android Tablet using BLUEDUO App to wirelessly control the a small SDR transceiver with spectrum/waterfall display. (Posted on 14/09/2016)

    This works well - haven't tested the range capability yet - but used for Bluetooth control is ideal. There are several free android apps available on the Google Playstore that can be used in conjunction with it.
    A word of warning though do not do as I did with the first one I bought. Take care to mount it somewhere it is protected from collision damage. I drove the first one under a lounge and broke it at the connector. (Posted on 7/09/2016)
