Arduino Uno Rev3 Microcontroller Board

Description

Overview

The Arduino Uno Microcontroller Board is the cornerstone of the Arduino platform, powered by the ATmega328P microcontroller. Ideal for beginners and seasoned makers alike, it offers 14 digital input/output pins (6 with PWM output), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. Everything you need to start your project is included—just connect it to a computer via USB or power it with an AC-to-DC adapter or battery. Its forgiving design means you can experiment freely; even if you make a mistake, the chip is affordable to replace.

Named “Uno” (Italian for “one”) to mark the release of Arduino Software (IDE) 1.0, this board is the reference model for the Arduino ecosystem. It’s a versatile platform for learning electronics, prototyping projects, or building everything from simple LED circuits to complex IoT devices. The Uno supports the Arduino IDE, Arduino CLI, and Cloud Editor, making programming accessible online or offline. With compatibility for a wide range of shields and libraries, it integrates seamlessly with sensors, motors, and more.

Certified with CE, FCC, RoHS, UKCA, and other global standards, the Arduino Uno ensures safety and reliability. Its open-source hardware design, complete with schematics and Eagle files, empowers you to customize or even build your own board. Whether you’re a student, educator, or hobbyist, the Uno’s robust community support, tutorials on the Arduino Project Hub, and active Arduino Forum make it easy to get started and find inspiration. From robotics to home automation, the Arduino Uno is your gateway to endless creative possibilities.
