The Arduino UNO R3 is the most widely used and beginner-friendly microcontroller board in the world. Powered by the ATmega328P chip, it offers an easy-to-use platform for learning coding, electronics, and hardware development. Whether you’re building a sensor-based automation system or a school robotics project, the UNO is the gold standard for fast prototyping and reliable performance.
This version comes without the USB cable, making it ideal for those who already have cables or are purchasing multiple units for classrooms, workshops, or bulk kits.
