10pcs Nano V3.0 Nano Board ATmega328P CH340 5V 16M Microcontroller Board, Electronics Development Board Nano 328P Nano 3.0 (10pcs)

• The Nano is using the chips ATmega328P and CH340, Replace FT232RL.
• 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 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.

The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 Nano 3.x). It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
