Product description

The Geekcreit UNO R3 is a fully Arduino-compatible board powered by an Atmega328p and CH340G serial interface. While a clone to the Arduino UNO R3, it functions exactly the same and is fully compatible with the Arduino Software (IDE). Clone UNO's can be manufactured under the creative commons files provided on the Arduino website.

This is a bare board kit, if you have a spare USB A-to-B cable and some headers or a shield you are good to go, save money and the environment by not adding another cable to that pile you already have. Our multi packs are great value if you are rolling out larger runs of the same project.
