Product Description

The UNO R3 is the latest easy-to-use open source controller released in 2012, with no significant hardware changes compared to UNO. The biggest difference lies in the USB to serial circuit, which uses an ATMaga16U2 microcontroller. As a result, the cost has also increased, and the software part remains the same as before, without significant changes.
Function:
1. Pin change: Two I2C pins (SDA and SCL, only copies of Analog 4 and 5, not additional I2C interfaces) have been added next to the AREF pins. In addition, two pins have been added next to RESET, one is IOREF, which allows the expansion board to adapt to the board voltage. This pin only tells the current board voltage of the expansion board (for example, UNO is 5V, which can be seen as a copy of the power pin and does not provide level pull-up), The other is a placeholder pin to be used in the future.
2. More stable RESET circuit. The position of the RESET key has also changed and has been moved to the corner of the board near the USB interface, making it easier to press.
3. ATmega16U2 replaces 8U2, which does not mean that having a 16K flash R3 can make your code run faster. This update is for USB interface chip services, theoretically allowing UNO to simulate USB HID, such as MIDI/Joystick/Keyboard.
