UNO R3 is a new easy-to-use open source controller introduced in 2012. There is no big change in hardware compared with UNO
The big difference lies in the USB to serial port circuit part
It is an ATMega16U2 MCU, so the cost is also Improve, the software part is the same as before, no big changes
Features:
1. Pin change: Two I2C pins are added next to the AREF pin (SDA and SCL, just copy of Analog 4 and 5, not an extra I2C interface),  In addition, two pins are added next to RESET, one It is IOREF, which can adapt the expansion board to the onboard voltage
2. More stable RESET circuit. The position of the RESET button has also changed, and it 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 R3 with 16K flash can make your code run faster. This update is for USB interface chip. In theory, it allows UNO to simulate USB HID, such as MIDI/Joystick/Keyboard
 
 
Feature Description     
Open original design circuit diagram, development software interface free download, can also be modified according to the needs, downloading program is simple and convenient. Simply use sensors, a variety of electronic components (such as: LED lights, buzzers, buttons, photoresistors, etc.) to make a variety of interesting works  
Using the high-speed microprocessor controller (ATMEGA328), the development interface and environment are very simple and easy to understand, which is very suitable for beginners to learn.
 
Performance Description Digital I/O digital input/output terminals total 0~13. The analog I/O analog input/output terminals are 0-5. Support ISP download function. Input voltage: no external power supply is required when connecting to the computer USB, external power supply 5V-9V DC voltage input. Output voltage: 5V DC voltage output and 3.3V DC voltage output. The Atmel Atmega328 microprocessor controller is used.

    Отличная цена. Кажется, точно как оригинал. Он работает так же, как Arduino, и прекрасно работает с оригинальным программным обеспечением Arduino.
