Key Features:

• The Nano is using the chips ATmega+328P and CH340, not FT232 as official Arduino, so pls. use the driver from our site.
• It is a smallest, complete, and breadboard friendly board. It has everything that Diecimila/Duemilanove has (electrically) with more analog input pins and onboard +5V AREF 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’s got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, 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 selected to the highest voltage source.
• Learn Arduino Nano with ease: Our ELEGOO Nano Board is the perfect choice for beginners and experts alike, with tutorials available to help you get started.
