Bluetooth Breakout and Free Shipping

I would like add yet another product to my online store, NJC's Bluetooth breakout board. I would also like to announce that there is now free shipping on all orders within the contiguous United States for items on my online store.

This board is based off of the RN-42 module which is very easy to use and add to your current projects. A few weeks ago I actually wrote a post on how to add Bluetooth to your MSP430 project that mentioned this breakout board. The circuit board is a modified design of SparkFun's Bluetooth breakout board which adds status LEDs and all the passive components needed to make this board "plug and play" right into your project while keeping all the important yet non-essential pins available. The module is also small enough that it can be added to existing projects with ease.

You have two options when buying this board, either completely assembled or as a bare PCB. The completely assembled board is a good option for those of you who don't want to fuss with surface mount components, and want a guaranteed working board. The bare PCB is a great option for those of you who have no problem soldering surface mount components and who want to add Bluetooth to their project while spending as little as possible.

The picture above shows the pinout of the board, which should make it very easy for you to incorporate into your project. You just need to connect the RX, TX, 3.3V, and GND to your project, and you are ready to go. The full schematic of the board can be downloaded below.

Interested? Pick one up at my online store!

Please let me know if you have any questions!

  1. Is this Bluetooth Breakout pinout compatible for LaunchPad Pinout? or we need extra wiring for MSP430 LaunchPad (MSP-EXP430G2)?

  2. No, this is not pin-out compatible with the LaunchPad. It can be connected directly to the LaunchPad via wires, or via a breadboard.

    I do have plans to sell a Bluetooth LaunchPad shield in the future. So stay tuned!

  3. This is great no soldering hustles for those who want to add Bluetooth in their projects.

  4. Just to be absolutely clear..

    The completely assembled board includes the RN-42 Module already soldered on, right?


  5. Yes. The completely assembled board has the RN-42 module soldered on. I also provide through hole headers (which are not soldered on) which you can use on abreadboard.

    Please let me know if you have any other questions.

  6. NJC,
    Thanks for the quick reply!
    Looking for a way interface the controller in an incubator I'm building to the outside world - need to send and receive time/temperature profiles - very low throughput.

    Wanted to be able to interface to a laptop or bluetooth device like an iPhone. Saw that iOS will only interface to a device that says it's a HID or PAN, not SSP, so this might be a limitation. Any chance you might have the RN-42-HID available in the future?


  7. Jeff,

    That project sounds pretty awesome! As I have not worked with the HID version yet, I do not plan on selling it. That being said, SparkFun does sell an HID module.

    If you can determine that the HID version is completely pin and footprint compatible with the regular version, I might be able to solder one up for you.

    Feel free to send me an email if you would like to discuss this further.
