Beautiful and aim to prevent electrostatic damage to the module
Can also be used as a pair which provides a transparent serial data communication
Working temperature: -20 - +55 ºC
The DFRobot Serial Bluetooth Module uses a unique double-board design, it is beautiful and aim to prevent electrostatic damage to the module. It is designed to have 2 DC power input, wide voltage supply (3.5V - 8V) and 3.3V power supply, suitable for various applications. It has build-in on-board antenna which provides high quality signals. It has been tested and compatible with most Bluetooth adapter in the market (Bluetooth dongle, including laptops and mobile phones). This module can also be used as a pair which provides a transparent serial data communication.

Great foundation for controlling tracked vehicle Rover. Implemented with Android Nexus 7 to make remote control. Eventually I will use to switch between remote control and autonomous navigation. Hope to be able to send picture files to PC and Nexus 7

Excellent module, will by another
An excellent bluetooth module. Works right out of the box but can also be reconfigured as needed. Will need this program to do so: http://180.150.162.233/en/Support/S_tools/459.html Read the datasheet provided by robotshop

Rookie
I am a rookie so it took some time to figure out the bt module. That being said, it works perfectly and a more experienced person would have had it up and running within minutes.
