New Ethernet Development board, open-source

Oct 07, 2005 0 Replies

Hiya all,



I just put out my new Dev. board that's open source, but I do sell assembled units. Thought I would just the link and some specs here for fun. Any comments are appreciated... the schematics/user-guide/pcb/bom are all available for download.
