A 16x16 RGB LED Matrix controlled by DMX over wifi

Some facts:


So this is the second LED Matrix we are building. The first one was a bit smaller (10x10) and used shift registers only for controlling the LEDs. We weren’t that happy about the limitation we got using shift registers only. We ran into refresh rate problems while trying to increase possible grayscale values. We ended up with 8bit grayscale (0-255).

The plan

So the basic data flow should look like this




The building process

main frame Backplate

So after some weekends of soldering 4 wires to every single SMD LED we finally made it.

First LED Soldering LEDs

Lets start soldering them on the frame…

First Process

After dozen weekends spend soldering we made it


First testing

As you can see. It works! :) But there are some LEDs that need to be fixed
