Arduino Uno R3 DIP Edition (Revision 3) - Genuine Microcontroller
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 the future, the shields will be compatible both with the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is a not connected pin — that is reserved for future purposes.
Stronger RESET circuit.
Atmega 16U2 replaces the 8U2.
Arduino Uno R3 DIP Edition (Revision 3) is a microcontroller board based on the ATmega328. This Arduino Kit is your starting point in the world of physical computing.
