About Arduino Nano V3: This is the latest version. This new board incorporates an ATmega328 chip which provides increased transfer speeds and bigger memory. THe Arduino Nano is a small, breadboard friendly version of the popular Uno.This board is more suitable for experienced users. We recommend the Arduino UNO board for beginners. This board is an Arduino compatible and is designed to be 100% compatible to the Arduino open source standard. Its layout strongly adheres to standard in both software and hardware; you should see no difference in quality or functionality to an equivalent Arduino brand board. Obviously, you can always return it if you are not satisfied within 14 days of receiving it and we refund your money.
