Nano 3.0 Atmel Atmega328P Mini-USB Board for Arduino – Blue

The Arduino Nano USB Microcontroller is a breadboard ready version of the Arduino mini with integrated USB The Nano has more analog input pins as compared to most Arduino boards and an onboard +5V AREF jumper. The Nano automatically senses and switches to the higher power power supply, so there is no need for a power select jumper Arduino Nano is a complete and breadboard friendly Arduino board. It has everything that Arduino UNO/Duemilanove has (electrically) with more analog input pins and relatively smaller size Arduino Nano is a surface mount breadboard embedded version with integrated USB. It is a small, complete, and breadboard friendly. It has everything that Diecimila/Duemilanove has (electrically) with more analog input pins and onboard +5V AREF jumper. Physically, it is missing the power jack. The Nano will automatically sense and switch to the higher voltage source of power, there is no need for the power select jumper. Nano’s got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space. It
