This is a new board I've made, called the Sanguino. Its an Arduino compatible board based on the beefy atmega644P chip. Its got 64k of flash, 4k of ram, and 32 GPIO pins. Its pretty sweet! Check it out: http://www.sanguino.cc

We did it! Arduino is fully ported to the atmega644: bootloader and core libraries both work great. I have a prototype board in production right now, and we just need to hash out the collaboration details with the Arduino core team. Once that is done, you'll be able to get your hands on an awesome, cheap, and powerful Arduino compatible board. Yay!

I'm in the process of porting the Arduino environment to the atmega644 for a skunkworks project I'm working on. This chip is awesome because it has 4x the flash (64k vs 16k) it has 4x the RAM (4k vs 1k) and 12 more I/O pins (32 vs 20) Its the biggest and baddest atmel chip that has a DIP version that I could find. Here is a video of my first major success where I wrote and uploaded an Arduino sketch to it.
