Arduino Nano 328P-AU with CH340 USB Driver

Description

Arduino Nano is a surface mount breadboard embedded. Smallest, complete, and breadboard friendly. It has everything that Diecimila/Duemilanove has. Arduino Nano is automatically sensed and switch to the higher potential source of power. No need for the power select jumper.

Nano’s got the breadboard-ability of the Boarduino and the Mini +USB with a 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). This new version 3.0 comes with ATMEGA328 which offer more programming and data memory space. It is two layers. That makes it easier to hack and more affordable. You end up paying less with Nano than Mini and USB combined!
