I have created a breakout board for this circuit for a more simple and quick build of projects and experiments. Take a look at http://www.instructables.com/id/The_Dawm/ where I have put a short instruction how to solder it together with some pictures. I also refer to your library acleone hope that is alright...
The nice thing of the breakout board is that it is easily connectable after each other creating a lot of outputs fast together with the TLC5940 library
If anyone is interested in a breakout board please mail me or soon look at http://blushingboy.org/ where it will be sold as soon as the page is ready...
