Arduino Uno R3 Microcontroller

The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

Overview

 Arduino Uno R3 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.

Revision 3 of the board has the following new features: 
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, shields will be compatible both with the boards that use the AVR, (which operates @ 5V) and with the Arduino Due that operate @ 3.3V. The second one is a not connected pin, that is reserved for future purposes.


*Note: This is not an original Arduino brand product, it is manufactured with the same components and functionality by a different manufacturer.
