This module has a built-in 3.3V voltage regulator and helps to break out the important pins. Based on CSR BC4 chip, Bluetooth V2.0 + EDR. You can set the baud rate, name and pair password by AT commands when there is no Bluetooth connection. This module is a slave- it can be paired with Computer- Bluetooth master- mobile phone- PDA- PSP and so on.

HC-06 is the popular Bluetooth module.  It’s very easy to add wireless serial connectivity for your device with this module. Examples for Arduino and other boards are available. Once you pair with other Bluetooth devices you work like with normal UART to exchange data.
