Uno R3 - Clone original FTDI ATML MEGA16U2 Description There are a few changes in the UNO, here is what they are ATmega16U2 instead of the 8U2 found. This allows for faster USB transfer rates. No drivers needed for Linux or Mac (.inf file for Windows is needed and included in the Arduino IDE) The ability to have the Uno show up as a keyboard, mouse, joystick, etc. New SDA and SCL pins next to the AREF. this is a duplication of the Analog 4 and 5 pins. Two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes.
