MakerChips has produced the smallest BTLE breakout board available.  The entire board is only 16.6 mm long and 11.15 mm wide but still makes 8 GPIO pins easily accessible with .1" headers, 4 more GPIO available via .05" headers and 2 bonus GPIO available as test points.   Along with the GPIO the .1" and the .05" headers expose the pins necessary for power and programming. The use of the Nordic NRF51 based Taiyo Yuden BTLE module means the entire package is FCC certified and can be incorporated into commercial products.
