Arduino Uno R3 board

ATmega328P Microcontroller Core: Powered by the classic ATmega328P 8-bit processor running at 16MHz, serving as the gold standard development board for beginners and experienced engineers alike.

100% Arduino IDE Compatibility: Fully supported across all major operating systems by the official Arduino IDE software, libraries, and vast open-source online code repositories.

14 Digital I/O & 6 Analog Inputs: Outfitted with 14 digital input/output pins (6 capable of PWM output) and 6 analog input pins to control sensors, relays, motors, and displays.

Plug-and-Play USB Interface: Features a standard USB Type-B port for effortless power delivery, code uploading, and serial debugging via an onboard ATmega16U2 USB chip.

Standard UNO Shield Layout: Universal R3 pin header geometry ensures seamless plug-and-play connection with hundreds of official and third-party expansion shields.

PCB & Hardware Quality: Built on a multi-layer FR-4 glass epoxy printed circuit board featuring a socketed DIP ATmega328P IC for easy replacement if needed.

Power Supply Tolerances: Operates on 5V DC logic. Accepts power via USB or 7V–12V DC through the onboard DC barrel jack or VIN pin. Do not supply over 20V to prevent damaging the regulator.

Handling & ESD Precautions: Practice standard anti-static handling procedures when touching exposed pin headers; always disconnect power before adjusting breadboard or shield wiring.

Environmental Limits: Operating temperature range is -10°C to +60°C. Keep protected from static discharge, metal particles, and direct liquid moisture.

Essential Beginner Platform: Market as the flagship, must-have starter board for students, hobbyists, and educators entering the world of programming and physical computing.

Durable DIP Chip Advantage: Highlight the socketed microcontroller chip design, which allows easy replacement if a pin is damaged during classroom experiments.

Recommended Cross-Sell Add-ons: Pair with USB Type-A to Type-B Cables, Solderless Breadboards & Jumpers, and Sensor Starter Kits.

Foundation for DIY Electronics: Excellent baseline choice for building robotics projects, automated environmental monitors, home security devices, and interactive art installations.
