NANO Version 3 is the open source smallest Embedded Development board based on Atmega328 SMD Package Microcontroller. It is a Surface mount Breadboard Friendly board integrated with Mini USB Port. DC Power Jack is not available on this Board, so power can be given through Mini USB Cable. It automatically sense and switch to the higher potential source of power, there is no need for the power select jumper.
