The Nano is using the chips ATmega328Pand CH340, not FT232 as official for .Small for Board:It is a smallest,complete and breadboard friendly board. It has everything that for /Genuino has (electrically) with more analog[A1]; input pins and on board +5V AREF jumper.More Breadboard Space: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's got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, , GND )on one top, power and ground on the other.The Nano can be powered via the Mini-B USB connection, 7-12V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically[A2]; selected to the highest voltage source.Usage: The Nano is compatible with for , with the same chips ATmega328P and CH340 with the official version[A3].Colour: blueMaterial: PC+metalPackage Contents:3 * microcontroller kitOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
