Pin change: Add two I2C pins (SDA and SCL, Analog 4 and 5 copy, not the extra I2C interface) to the AREF pin. ATmega16U2 instead of 8U2, this does not mean that there are 16K flash R3 allows you to run the code faster, this update is a USB interface chip services, in theory, it allows UNO to simulate USB HID, such as MIDI / Joystick / Keyboard.
