Arduino UNO R3 ATMEGA328 - Compatible ​with bootloader
 
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. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an 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 future, shields will be compatible      both with the board that use the AVR, which operate with 5V and with the      Arduino Due that operate with 3.3V. The second one is a not connected pin,      that is reserved for future purposes.
 
Stronger RESET circuit.
 
Atmega 16U2 replace the 8U2.
"Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform.
