Keyestudio Uno R3 is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter. 
1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and for Arduino Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes.

Features:
Excellent board and great quality! 
Stronger RESET circuit.
Atmega 16U2 replace the 8U2.
Both affordable and portable for your Arduino learning. 
This UNO R3 for Arduino from Keyestudio works fine with original software and looks very very good in black/yellow color. 
Suitable for all kinds of scientific experiment research for Arduino.
