Hello, I am designing a board that is based on the Ethernet booster pack that, I believe, Rob made, as well as integrate SD card holder as well. I am planning on using both, since I bought both of them, to build a new platform for the LaunchPad. I will have 56K of code space, and 4K of SRAM, I will post some schematics as I go on. It will be open source and I am hoping that everybody will like it, and will keep you updated.
