DESCRIPTION:

• Arduino UNO R3 – DIP development board & USB cable
• Microcontroller: ATmega328
• 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
• Stronger RESET circuit
• Atmega 16U2 replaces the 8U2
• Comes with USB cable
