Freematics Nano Kit (Arduino Nano based)

This kit contains basic components needed to put up a device that can read vehicle data and display it on a OLED display module. You can place it anyway on your dashboard that you feel comfortable or make a enclosure for it.

Hardware

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (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 Mini-B USB cable instead of a standard one.
