Arduino Uno Rev 3 Boards


The Arduino Uno board is a microcontroller board based on the ATmega328. The Arduino Uno Rev 3 boards we have for sale contain 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. We also sell Arduino tinker kits, development components and sensor shields you can add to this package but it all starts with the Uno R3 microcontroller.

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U programmed as a USB-to-serial converter.
