Expansion boards allow you to add many lights at one time or even connect multiple boards together.  Can also add one to an effects board.

More and more lights!

The power source connects to the expansion board.  Now, all lights that are plugged into the expansion board will light up!
You can connect more than one expansion board together with our connecting cables (not included with expansion boards).

Expansion boards can be used to add multiple lights to one effects board.  If you connect an expansion board to the out port of an effects board, all lights will all display the effect simultaneously.  

ALWAYS insert and remove these lights by holding the plug.  Removing the lights by pulling on the wire can result in damage.  To remove the light from a port, grip the plug with your finger nails and pull.
