I agree, eagle files would be very cool. :)

The LED Matrix I recieved uses an Atmega 168 while the sample code seems to be written for Atmega 8 with an old version of the gcc-toolchain. I updated the self-control firmware example like thus: http://pastie.org/321922

Please update schematic. You are shipping v08 of this board, the schematic indicates v03. Thanks, Justin

Please update product images and downloadables to current version (no v. info printed on board but it's not v08n anymore). Svealebor's pastie'd code with some changes (e.g. rowmap) works for me.

Could you run this at 3.3V instead of 5V? Understand ATMega @ 16 MHz isn't officially rated for 3.3V, but I have used them over clocked and they work fine. I assume the LED matrix would be dimmer and consume less power which is fine for my application.
