This board allows you to connect the programmable LED light strip as well as the userport adapter board to the same port on your Ultimate 64.

This board breaks out the 5V, CLK, SDI and GND pins so that you can easily plug your light strip directly into your Ultimate 64 while still having your user port adapter board connected.

Take note that the Ultimate 64 Elite v1.4 has these pins already broken out on the board, so this is not needed for that version of board.  This can be used on all previous versions.
