General Description:

ATmega16U2 :

 UNO R3 is an easy-to-use open-source controller newly launched in 2012.  There is no big change in hardware compared to UNO. The difference lies in the USB to the serial circuit. An ATMega16U2 microcontroller is used instead, which also increases the cost. The software part is the same as before, without major changes.

Features:

1. Pin changes: Two I2C pins have been added next to the AREF pin (SDA and SCL, which are only copies of Analog 4 and 5, not additional I2C interfaces). In addition, two pins have been added beside RESET, one is IOREF It can make the expansion board adapt to the onboard voltage. This pin only tells the current onboard voltage of the expansion board (for example, UNO is 5V, which can be regarded as a copy of the power pin and does not provide level pullup). Standby pin.

2. More stable RESET circuit. The position of the RESET key has also changed, and it has been moved to the corner of the board near the USB interface for easier pressing.

3. ATmega16U2 replaces 8U2, which does not mean that R3 with 16K flash can make your code run faster. This update is for the USB interface chip. In theory, it allows UNO to simulate USB HID, such as MIDI / Joystick / Keyboard.
