Quick Overview

Latest Arduino Uno, revision 3. This is the newest Arduino microcontroller board based on the ATmega328. Compared to Duemilanove, Uno has custom USB-to-serial chip based on ATMega8 which does not require any drivers to be installed. 100% compatible with previous Duemilanove.

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 a AC-to-DC adapter or battery to get started.

 



The Arduino Uno rev.3 is the latest version of Arduino microcontroller board based on the ATmega328.

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. Summary:

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.

 

  • Microcontroller ATmega328
  • Operating Voltage 5V
  • Input Voltage (recommended) 7-12V
  • Input Voltage (limits) 6-20V
  • Digital I/O Pins 14 (of which 6 provide PWM output)
  • Analog Input Pins 6
  • DC Current per I/O Pin 40 mA
  • DC Current for 3.3V Pin 50 mA
  • Flash Memory 32 KB (ATmega328) of which 2 KB used by bootloader
  • SRAM 2 KB (ATmega328)
  • EEPROM 1 KB (ATmega328)
  • Clock Speed 16 MHz
