Alright guys so you have built your Virtual Pinball Cabinet Flat Pack and your ready to assemble and install your LED Matrix Board. I would highly recommend Cleveland Software Design's Addressable LED Plug and Play Kit.

This is a super easy to install and setup kit. Phil's tutorials are great and so is his customer Service.
Step 1 glue the 2 thin riser boards to the main board. Try and keep these even to the edge of the main board. We use the top board as a guide for lining up the addressable LED panels.
Wait for the glue to dry. Feel free to add some screws thru the back after the glue has dried.
Step 2 is now remove all the LED Panels from the LED Panel frames. Line them up so they are nice, neat and centered on the LED Matrix board.
Step 3 use some small screws and screw down the LED panel frames to the LED Matrix board
Step 4 once you have screwed these all down and your happy with the positioning add the LED panels back to the frames and run the wires thru the back of the frames and the LED matrix board.
Next plug everything in the CSD controller board download the CSD Addressable LED software and run some tests to be sure all of the panels are working.
Last step is to use the 4 small Velcro pads and install them in the 4 corners of the riser boards and the plexiglass then attach the plexiglass to the LED Matrix board!!!!
Your all set and ready to install it in your Virtual Pinball Cabinet!!
