Arduino Nano v3 Compatible

ATmega328 with CH340G and MicroUSB

This Arduino Nano compatible module is a small, complete and breadboard friendly design. Designed around the ATmega328 which is the same as the original Arduino Nano 3.x. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Micro USB cable instead of the less common Mini USB..

For added protection, the board has an auto rest fuse to protect the on-board electronics.

Technical Specifications

Unlike the original Arduino Nano v3, the USB interface used a Mini USB B connector. This new design uses the more popular Micro USB B connector.

Note: This unit includes two headers of 15-pins and the six pin expansion connector. These will requiring soldering on to the processor Nano board.
