BLE112-A Breakout Board v0.5.0

Hello BLE112 hardware developers,

to make hardware development a little easier, I simply created a BLE112-A Breakout board for you that can be used on a breadboard. I added three 100nF block capacitors and the programming header for the CC-Debugger to the breakout board. I’m open for suggestions, since the board is in version 0.5.0.

The eagle design files and the PDFs of the schematic and board files can be found in the “BLE Other Files” box on the blog’s main page.

    How would I acquire such a board?
    Are these in production? Is there a possibility to acquire a prototype?

    Many thanks,

      I don’t believe so. If you want one you download the eagle files and use a mill as far as I know.

    Dear Micheal,

    Where can I buy this module?

      I have some bare PCBs here but no BLE112. If you are interested in soldering manually I can send you some 😉

    Hi, did you wind up producing these? Looks great, I’d just suggest adding a reset button

    • Michael Kroll December 11, 2012 at 21:16 #

      No, i just created some for testing but never thought about selling them.

    • Michael Kroll December 11, 2012 at 21:17 #

      But I have about 10 bare PCBs arround. Interested to purchase them for the production cost?

    I am interested in buying your PCBs. How much do you want for them? Please contact me via email.

    I just sent your boards (BLE112 Breakout) to be manufactured. I haven’t got them back yet, but I believe there might be an issue.

    I do not believe the grounds (“GND”) of the capacitors are tied to anything.

    I believe you meant to tie them to “1-GND” ?

      Hi Peter,
      I built some but never tested them.
      I’ll take a look into it and make an update asap.

        Hi Michael,

        I fixed that on my copy and also I added a reset button and 5v input pin on the left header that connects to a LDO 3.3 V regulator (that will work with an input from @4.5v to 20v) and outputs to the AVDD circuit.

        I was really hoping that you were going to say that you were using them and it didn’t seem to matter! I am wondering if they will work without them, have you given any to other people?

        I am trying to get a start on playing with the BLE112, I am currently using the redbear BLE shield. The BLE112 seem much more useful, but obvioulsy more complicated to implement.

          Hi Michael,

          If you or anyone else is interested, I have placed the eagle files for my versions on my website. They include as mentioned a 3.3v regulator and also eliminates via’s under the BLE112 as specified by Bluegiga (do to the BLE112 having a grounded underbelly).

          Feel free to copy/ use/ modify! Also be sure to let me know what you guys think. I will be modifying the future design based on feedback.

          Thanks again for placing so much valuable information on your website, it has been a great help to many, inclusing myself.

            Hi Peter,
            I fixed the bug with the not connected GND lines of the capacitors and added a reset switch as well. I changed the capacitor and resistor packages to 0603 now. I ordered two prototypes of the board for testing before I will share the design files.

    Hi Michael,

    I am interested in using a BLE112 breakout board for one of my projects. Can i buy an assembled board from you?


    • Michael Kroll March 25, 2013 at 17:13 #

      Hi Akshay,
      I do not have boards for sale at the moment. Sorry.

  7. Denny July 3, 2013 at 12:11 #

    Hi Michael,
    do you have any further of these Breakoutboards or do you know where to buy in Germany?
    I only need the board without the electronic components on it and I need it as soon as possible. If you have one, I could pay with Paypal.

    HI Michael,

    I’m a begineer in electronik conception and I have as final study project to devlop a board with blue low energy(ble 112) with sensor.

    I need some help.

    Can You help me?

    Hi, can i ask you, how can i supply this board? I dont see any USB port or battery holder. I must supply it with wire/cable? On which pins? Thank you for answer 🙂

    • Michael Kroll March 1, 2016 at 09:59 #

      Hi Marek

      well this board simply breaks out all pins. You need to wire them yourself using e.g. a bread board.


      • Marek March 11, 2016 at 16:32 #

        And one more questions 🙂 On X1 is port 9. It must be connect to 3,3V or not? Some people have connected port 2 and 9. Thank you

        • Michael Kroll May 26, 2016 at 20:54 #

          Sorry, I don’t really understand your question.
          What X1 are you talking about?


      • Marek April 4, 2016 at 16:11 #

        Can u give me answer please 🙂
