nRF51 E3 BO

The adapter board, nRF-e3-BO for the low cost nRF51822 modules is now available for sale. There a number of cheap (≈ USD 5) nRF51822 modules which  use dual 2x9 2mm pitch male header pins, making them very difficult to use. This modules breaks out the pins to standard 2.54mm pitch headers, which aptly fit on a breadboard or perfboard. The board has 5v to 3.3v voltage regulator on board. The board also breaks out Serial Wire Debug(SWD) pins for programming and debugging. The board is result of collabration between Explore Embedded and Mahesh Venkitachalam from electronut.in. 

Note: The nRF51822 module is not shipped with board. You can get it here.
