This is an arduino compatible Bluetooth Shield which integrates a Serial Bluetooth module BLK-MD-BC04-B, it is very easy to use with Arduino Board for transparent wireless serial communication, you just need to directly plugg it into the Arduino control board,which can be extended for the Arduino Bluetooth communication capabilities. Meanwhile, the expansion board is stackable and can be stacked on this basis and other expansion boards.
You can choose two pins from Arduino D0 to D7 as Software Serial Ports to communicate with Bluetooth Shield (D0 and D1 is Hardware Serial Port).
Please note: The Shield may not be compatible with some Bluetooth capable devices, like Apple devices with special profile on Bluetooth function.
