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