Description

The Arduino Uno is a microcontroller board based on the ATmega328. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 6 can be used as analog inputs), a 16 MHz resonator, a USB connection, a 2.5mm center positivce power jack, an in-circuit serial programming (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 Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter. This auxiliary microcontroller has its own USB bootloader, which allows advanced users to reprogram it.

The Arduino has a large support community and an extensive set of support libraries and hardware add-on “shields” (e.g. you can easily make your Arduino wireless with the Wixel shield), making it a great introductory platform for embedded electronics.

This is the 3rd revision of the Uno (R3), which has a number of changes:

  • The USB controller chip changed from ATmega8U2 (8K flash) to ATmega16U2 (16K flash). This does not increase the flash or RAM available to sketches.
  • Three new pins were added, all of which are duplicates of previous pins. The I2C pins (A4, A5) have been also been brought out on the side of the board near AREF. There is a IOREF pin next to the reset pin, which is a duplicate of the 5V pin.
  • The reset button is now next to the USB connector, making it more accessible when a shield is used.

More information about the Arduino Uno R3 is available on Arduino’s website.

* The Arduino Uno has 20 total available I/O lines; all of them can function as digital I/O lines, and six of them can be used as analog inputs.

Notes

  1. All 20 can be used as digital I/O and 6 can be used as analog inputs
  2. An external programmer is required for setting the fuses or upgrading the bootloader.
