This version is in the original version of the optimization, mainly for foreign customers on product quality and functional requirements of the case of high design, both to ensure that the original and fully compatible with the same, but also easy to use.

Advantages:
1 completely solve the traditional for UNO board win7 and win8 system is not compatible with the above instability. Especially in the pirated 64-bit WIN7 system, the official board can not be installed driver, and this version is very simple and easy to install.
2. Increase the pin socket, easy to use DuPont line.
3. Replace the 16u2, so that the cost reduced to half, consumers get the most benefits
