Description

Official Arduino Uno Rev3 Development Board (A000066)

The Official Arduino Uno Rev3 is the most popular Arduino board, powered by the ATmega328P microcontroller. It features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, USB connection, power jack, ICSP header, and a reset button.

The board contains everything needed to support the microcontroller. Simply connect it to a computer with a USB cable or power it using an AC-to-DC adapter or battery to get started.

The Arduino Uno is beginner-friendly and robust. You can experiment freely without worrying too much— in the worst case, the DIP microcontroller can be replaced easily at low cost.

The name “Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno Rev3 became the reference model for the Arduino platform and remains one of the most widely supported boards worldwide.

Getting Started

All the information required to configure the board, install the Arduino Software (IDE), and start coding and electronics experiments is available through official Arduino documentation and community resources.
