WYPH Nano Terminal Adapter for Arduino Nano V3.0 AVR ATMEGA328P-AU Module Board This item is a terminal expansion adapter, designed for Arduino Nano V3.0. The board is fully assembled. No soldering required. It can work very well for prototyping Arduino Nano projects. It provided a nice platform for wiring circuits to Arduino Nano. It can connect a large number of digital lines to Arduino while maintaining the footprint of the original Nano. You can use this adapter to easily hook up Arduino Nano to an outside world via hook up wires, and It can be used in conjunction with or in place of a breadboard. It lables for Arduino Nano version 1.0, however you can still use this adapter for the new version V3.0.
