There are many ATmega32u4 boards available, but the Ivory Circuit's breakout does break out every i/o pin of the micro. You still need to consider the use of pins like the HWB PE2 and the appropriate bootloader code, but other boards do not have this capability. I am using it to build a now-unavailable device called the phatIO which made accessible all i/o pin of the 32u4. This breakout board is a great way to create one-off/prototype designs.

Thank you for taking the time to share your feedback. We really appreciate that.
We are glad to hear that our boards have been crucial in your design process. It sounds really interesting. Certainly, one of our design goals for the Nakeduino was to be able to access every pin from the MCU.
We would be thrilled to see the final result of your design!
I ordered this product from Massachusetts, US and I received it super fast! (within 6 days). Well packaged and just like described in the product page. You can use this board as a standalone Leonardo or if you want you can use it as a USB interface for your project by flashing Lufa to the Atmega32u4. Great product, highly satisfied, thanks a lot!

We're glad to hear that you got everything on time.
It seems that you're having fun with the board and that's pure awesomeness.
Please let us know if there's something we can improve.
