Description: Replacement: None. We are no longer carrying this board. This page is for reference only.

This is the very popular Arduino platform with a Bluetooth****serial connection in place of the USB connection. Now you can have Arduino without wires!

Not sure which Arduino or Arduino-compatible board is right for you? Check out our Arduino Buying Guide!

Note: A portion of this sale is given back to Arduino LLC to help fund continued development of new tools and new IDE features.

Features:

  • The use of a DC-DC converter, allowing the board to be powered with a minimum of 1.2 V, but with a maximum of 5.5 V. Higher voltages or reversed polarity in the power supply will kill the board.
  • A surface-mounted ATmega328
  • Pin 7 is connected to the reset pin of the Bluetooth****module.
  • Only use serial communication at 115200 baud; this is the speed that the module has been configured to use.

The Bluetoothmodule used is the Bluegiga WT11, iWrap version (details and datasheet on the Arduino page). The Bluetoothmodule can be configured with commands set over the serial port from the ATmega328 (see the iWrap user’s guide for details). A program to set the name and pass code of the Bluetoothmodule is run once on each Arduino BT. The name is set to ARDUINOBT and the pass code to 12345. For complete details, see the initialization program’s source code. The ATmega328 comes preloaded with a bootloader that allows you to upload sketches to the board via the Bluetoothconnection. The bootloader source code is available in the Arduino SVN repository.

  • This picture is wrong, just an fyi

  • Hi, there don’t seem to be that many Bluetooth choices out there, and what is out there is fairly expensive – either the board is expensive or the shield is expensive. We built an Arduino-clone (ATMega328) with a Class1 Bluetooth modem http://daisyworks.com – here’s some observations on its range: http://daisyworks.wordpress.com/2011/08/08/bluetooth-range-observations/ – the cool thing about this board is that you can do firmware-over-the-air with Android or a Mac, Linux, Windows computer – and then you can control the device from your phone or a desktop computer. It may be interesting for someone looking for a Bluetooth project.

  • What is a good replacement for that?

  • Why are you not carrying this product anymore? Is the Arduino bluetooth an end-of-cycle product now? Is there a new version or redesign on its way?
    Are there any alternatives? I mean, I do not simply need an Arduino with a bluetooth chip that can use the serial profile … I need a bluetooth chip that implements the HID profile.
    Thank you very much.

  • does anyone know what model diode comes on this? the one connected to the leads of the screw terminal.

  • No offense, but that is one ugly board.

  • Whats the effective indoor range…?
    Are their any shield options…?
    -Tim

  • can this do multipoint bluetooth? i need simplex communication from one arduino to both another and an iphone.

  • What an insane price…

    • You’ll find that everywhere unfortunately. The Arduino Bluetooth has always been an expensive model.
      There are alternatives with the wide range of Arduino’s and Bluetooth boards here and elsewhere.

  • 1-Does the Arduino BT Kit supports iWrap2 or iWrap3
    i.e. the bluetooth module inside the Arduino BT kit is WT11-A-AI or
    WT11-A-AI3?
    2-Could I easily replace WT11 in the Arduino BT Kit with WT41 ?

  • How did you get the BT module to work with the Arduino bootloader? I’ve been trying to get a Bluesmirf Gold to do this for ages and failing! I don’t see anything to reset the the MEGA168 chip on the schematic, what is the PD7 connection to the RES line on the BT module for?
    Thanks!

  • Would i be able to connect to this with my Windows Mobile Professional 6.1 device and make an app for it that talks to it like was it a serial port?
    (aka. does WM recognice a SPP device?)
    Grats, Martin Munk :)

    • Hi Martin
      WM6 bluetooth stack supports the Serial Port Profile so development of an WM6 application to talk to the device should be possible.

  • Hi, do I need to do bootloader when I got this?
    Thanks!

  • Is there a way to send a signal from a wireless EMG device to this arduino board? My goal is to have the arduino board receive the signal from the EMG and in turn set off an LED light.

    • You’d have to make sure your wireless EMG device could pair to this bluetooth. Otherwise, you may need to look into RF modules.
