arduino bluetooth shield Arduino Bluetooth Expansion Board Green

Arduino Bluetooth expansion board plugged directly into the Arduino control board can be extended the Arduino Bluetooth communication capabilities. Use the Bluetooth expansion board to the Arduino's hardware serial port, and other non-serial expansion boards stacked together - such as Ethernet expansion board, SD expansion board.

Expansion board provides two switch. One is to select a compatible level - 5V or 3.3V. General Arduino expansion board direct support for the Arduino's 5V level, but did not take into account other Arduino compatible development board may use the 3.3V level, for example, based on the STM32 Leaf Maple based on PIC chipKIT.

Bluetooth expansion board inserted in the Arduino on, you can dial through another switch to select the serial port connected to the Arduino, accept ATMega328 control, or directly through FT232RL connected to the computer - this time you can use the Arduno IDE or other serial assistant with Bluetooth communication
