Mine were not connected, but I determined that they are for status LEDs.  Top pins toward the outside of the board are power and inside pins are ground.  From the outside of the board going inward, the first column is power status.  I am guessing, since it goes high when powered on and takes a long to turn off, guessing it is all of the caps.  The next one in is some sort of status.  It seems to blink randomly.  I am guessing it is reporting transactions between the mining ASIC and cgminer.  The rest of the pins do not see to do anything, that I could tell.  I have a friend who got his Baby Jet and these same two sets of pins are connected to the white LEDs on the top of the Baby Jet sticker on the front panel.
