Arduino Bluetooth expansion board plugged directly into the Arduino control board can be extended the Arduino Bluetooth communication capabilities. Meanwhile, the expansion board is stackable and can be stacked on this basis, the other expansion boards, and more features.
Features: • Onboard 3.3V-5V level conversion • Onboard IIC/I2C socket and digital port outlet • ESD static protection • The power indicator and status indicator • Support for any software serial port or hardware serial • Software-aware Bluetooth connection status
The Bluetooth Shield integrates a Serial Bluetooth module. It can be easily used with Arduino/Seeedstudio for transparent wireless serial communication. 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). The shield also has two Grove connectors (one is Digital, the other is Analog) for you to install Grove modules.
Note: The Shield may not be compatible with some Bluetooth capable devices, like some HTC mobile phone (G7 with Android 2.33) and Apple devices with special profile on Bluetooth function.
