Overview

Arduino Uno R3 (Compatible)

The Arduino Uno R3 is where most Indian electronics engineers begin. ATmega328P-based, with 14 digital I/O pins, 6 analog inputs, and a 16MHz clock — it is the most documented microcontroller board on earth. If something goes wrong, the answer is one search away.

Compatible Board — What Does That Mean?

This is a high-quality compatible board using the CH340 USB-to-serial chip instead of the original ATmega16U2. Functionality is identical for 99% of projects. The CH340 driver is free and installs in under a minute on Windows, Mac, and Linux.

Key Specifications

  • MCU: ATmega328P @ 16MHz
  • Flash: 32KB (0.5KB used by bootloader)
  • SRAM: 2KB
  • Digital I/O: 14 pins (6 PWM)
  • Analog Input: 6 pins (10-bit ADC)
  • Operating voltage: 5V
  • Input voltage: 7-12V (barrel jack)

Best For

Beginners, classroom projects, final year engineering projects, robotics prototypes, and any project that benefits from the massive Arduino library ecosystem. Pair with our L298N Motor Driver for robot builds or the HC-SR04 for distance sensing.
