This site includes the board layout and code to make this ATmega128 powered LED sign. If you speak German here is the original German site.
“Again such a crazy project of me. It began with the fact that I with EBay a mountain LED of modules ersteigert. And from this this enormous LED became panel. Whom is too enormous, there is also a small brother.
Here times the technical data:
* 128×64 two-colored LEDs
* approx. 80×40cm largely
* Power input computationally max. 110A/5V = 550W
* Ethernet interface
* Processor ATmega128 with 16MHz ”

Anyone have more info on the modules? A quick search on ebay didn’t return anything of value.

I think he used the Samsung SLM1606 or SLM1608 LED Panels. The panels only have different size. But the chances to get them are not very good, because they are no more produced. Only oddments were sold on ebay and elsewere.
If you unterstand german, you can get more information here:
