• Arduino Uno R3

Arduino Uno share the same components, characteristics and quality of manufacturing. They are actually the same board under a different brand. Depending on the area of the world where you live you’ll be able to purchase an Arduino Uno or a Genuino Uno. Learn more.

Uno Rev3 is a microcontroller board based on the ATmega328P, an 8-bit microcontroller with 32KB of Flash memory and 2KB of RAM. 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 board is the first in a series of USB boards and it is the reference model for the Genuino platform; for an extensive list of current, past or outdated boards see the Comparison Page.

The Uno is open-source hardware! These are the relevant files:
