Arduino Uno R3 SMD Board with USB Cable 🔧

The Arduino Uno R3 (SMD) is a reliable, open‑source microcontroller board built around the ATmega328P. Ideal for electronics engineers, students, and makers, it delivers a proven platform for prototyping with 5 V logic, abundant I/O, and broad compatibility with Arduino shields, electronics components, and modules. Program and power it via USB, or deploy it standalone with an external voltage source.

Why Choose This Board ✅

• Versatile compatibility with sensors, actuators, and standard Arduino shields for rapid prototyping.
• Easy to use with the Arduino IDE on Windows/macOS/Linux—perfect for beginners and advanced users alike.
• ATmega328P @ 16 MHz provides dependable performance for robotics, automation, and IoT-ready projects.
• Abundant I/O: 14 digital I/O (6 PWM) and 6 analog inputs for interfacing with diverse electronics components.
• USB connectivity 🔌 for programming, serial debugging, and power from your computer or USB supply.
• Open-source ecosystem with extensive libraries, examples, and community support.
• SMD edition: compact, durable design using the ATmega328P in SMD package (non-socketed MCU).

Highlights for Engineers 🛠️

• Compatible with Arduino libraries for SPI, I2C (TWI), and UART communication.
• Seamless integration with Raspberry Pi as a peripheral via serial/I2C/SPI (use level shifting for 3.3 V systems).
• Stable onboard regulation for 7–12 V recommended VIN input and 5 V logic rail.
• Standard Uno R3 footprint for shield compatibility and breadboard-friendly headers.
