Description: This is a low cost compatible alternative to the standard Arduino branded Arduino Uno R3. We have tested it and used them in a few projects. These compatible Uno R3s do all of the same things as the Arduino branded Uno R3.

In addition to all the features of the previous board, the Uno now uses an ATmega16U2 which allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE). Plus the ATmega16U2 allows the Uno to show up as a keyboard, mouse, joystick, etc.

The Uno R3 has the newer R3 style pin out which adds SDA and SCL pins near the AREF pin, plus an IOREF pin. This means the Uno is compatible with old shields and can also be used with newer shields that use these additional pins.
