Description
The HC-05 Bluetooth Module can be used in a Master or Slave configuration, making it a great solution for wireless communication. The HC-05 will work with a supply voltage of 3.6VDC to 6VDC, however, the logic level of RXD pin is 3.3V and is not 5V tolerant. It can be damaged if connect directly to a 5V device (e.g Arduino Uno and Mega). A Logic Level Converter is recommended to protect the HC-05. The power to the HC-05 will cut off if the "EN" pin is pulled to logic 0. You can use it simply for a serial port replacement to establish the connection between MCU and GPS, PC to your embedded project, etc.

The HC-06 Bluetooth Module is the easy to use and popular Bluetooth module. This HC06 module works in slave mode only. It’s very easy to add wireless serial connectivity for your device with this module. Once you pair with other Bluetooth devices you work like with normal UART to exchange data. This module has built-in 3.3V voltage regulator and helps to break out the important pins (Vcc, Gnd, Txd, Rxd). 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 etc.
