- 16x32 LED panels - not all LED panels are going to work - LED panels come with certain pin and LED configurations. This tutorial works great with the Adafruit LED panels. You can build a wall of any size really, but for the 2'x2' wall we used 18 panels
- LED video wall sender/receiver set with IDC adapter plate from Adafruit - they comes preprogrammed for this tutorial.
- You will also need 16-pin IDC connector and thick 5V power cables for the above. Our panels come with them. Make sure you have 18
- Long 16-pin IDC cables. These are to connect from the board to the first row of panels, for this design you'll need 8. Make yourself or buy from a cable assembler.
- Oval T-nuts, two bags
- 3/16 nylon spacer that will fit M4 screws - get a bag of 100
- 1/2" (12mm) M4 screw - get a bag of 100
- Double size Slotted aluminum extrusion - Five 2' long pieces
- Slotted aluminum extrusion - Four 2' long pieces
- L-plate for extrusion - Four pieces
- M4 10mm screws and slim T-nuts - one pack each
- 5V power supply with at least 20A output, 30A is better. A big ATX power supply can do this and is available at many computer supply shops
- ATX power adapter cables can be useful if you're using an ATX supply. Cut the yellow wire out so you don't accidentally send 12V into your panels
- 12 AWG stranded core wire - red and black, get a couple feet.
- Ring terminals that will fit 12 AWG - these may or may not be used depending on the panel power plugs
- Zip ties
- Heat shrink
- 5V 1A power supply with 2.5mm jack. This is not a standard size jack, but we used our compact switching adapter with multiple jacks and it works. Just make sure you use 2.5mm with center positive and select 4.5V on the adapter.
- Ethernet cable - we used up to 100 ft long cable with success, any Cat5 cable ought to work. We have up to 10ft long in the shop
- Access to a computer with Windows XP/7 if you want to run the configuration software - the config software only needs to be run if you want to change around the display configuration
Also, a variety of tools! Hacksaw, Allen wrenches, heat gun for heatshrink, wire cutters & strippers, etc.
