UNO R3 2012 a new easy-to-use open source controller, hardware compared with theUNO and no major changes, the biggest difference isthat the USB-to-serial circuit part, instead, is a ATMega16U2 microcontroller, which costimproved software part before, there are no majorchanges.

Functions:

1 pin of changes: next to the AREF pin both I2C-pin (SDA and SCL, just Analog 4 and 5 of the copy, not the additional I2C interface), plus thetwo next to the RESET pin, one IOREF allow expansion board voltage onboard, this pin expansion board just told the onboard voltage (such as UNO 5V, can be seen as the power pins copy, does not provide the level pull), the other is later Scratch placeholder pin.

2 more stable RESET circuit. The RESET key position has changed, has been moved to the corner near the USB interface board, more convenient and press.

The 3. ATmega16U2 instead 8U2, and this does not mean that the 16K flash of R3 to make your code run faster, this update is a service ofthe USB interface chip, theoretically It UNO can simulate USB the HID, such as MIDI / Joystick / Keyboard.
