Bluethooth Module

Introduction:

This DF-Bluetooth module offers an affordable way to let your microcontroller talk to your bluetooth devices such as bluetooth mobilephones, laptop, and bluetooth adapter. The bluetooth module provides TTL level UART interface which is supported by almost every microcotnroller in the market.

It is also designed to be compatible with popular Arduino controller. Simply plug into Arduino IO Expansion Sheild or connected by four wires, a Bluetooth Arduino is ready to use.
