Virtuabotix Bareduino - Barebones Arduino Compatible Microcontroller
Need lots of Arduino compatible controllers, but don't need the price tag that comes with a full development platform? This handy little kit is perfect for anyone who is experienced with the Arduino platform, and needs to include a lot more of them in his/her next project. Make a project on a breadboard, tie as many ATMEGA328's together as you need to. The sky is the limit, and you don't have to buy in bulk to get a great deal!
