Introducing the Arduino Uno R3 with Cable, the ultimate microcontroller board for beginners and seasoned makers alike. This iconic board, based on the ATmega328P microcontroller, is the cornerstone of countless projects worldwide, from simple LED circuits to complex IoT systems. Whether you’re a student learning to code, a hobbyist building a robot, or a professional prototyping a smart device, the Arduino Uno R3 offers unmatched versatility, ease of use, and a vibrant community to support your journey.

The Arduino Uno R3 stands out with its 14 digital I/O pins (6 of which support PWM) and 6 analog input pins, giving you ample flexibility to connect sensors, actuators, and displays. It features a 16 MHz crystal oscillator for reliable performance, a USB Type-B interface for programming and power, and a 5V operating voltage that’s compatible with most shields and modules. With 32 KB of flash memory (0.5 KB used by the bootloader), 2 KB of SRAM, and 1 KB of EEPROM, it provides sufficient space for your sketches and data storage. The included USB cable ensures you can start coding right out of the box, connecting seamlessly to your computer for programming via the Arduino IDE.

Designed for accessibility, the Uno R3 supports a wide input voltage range of 7-12V (via the barrel jack or VIN pin) and includes an onboard voltage regulator to deliver a stable 5V and 3.3V output. Its automatic power selection between USB and external power makes it user-friendly, while the reset button allows for quick restarts during development. Measuring just 68.6mm x 53.4mm and weighing around 25g, this board is compact yet robust, perfect for both breadboard prototyping and permanent installations. The ICSP header enables advanced programming, and the LED on pin 13 offers a built-in testing feature for beginners.
