AVR Development Board

My instructable is about AVR board which I designed it by myself after doing some researches in google and watching some videos (specially Ben hack show) and decided to make this instractable. I know there is a lots of project out there but I decided to make a development board which have three type of popular AVR microcontrollers on the board and you can carry it very easy and use each of the microcontrollers when ever you want.”
