This beautiful little board for ATMega128 development was made by Olimex, and provides lots of I/O to help get your project running quickly. There are detailed specs at this Olimex page, including links to PDF manuals, demo code, schematics, and a complete open-source weather station. We only have one of these for sale; our new research vessel has standardized on the Arduino platform, so this is no longer needed. It has been tested with the supplied demo code, but never been fully in use.
