The Arduino Uno SMD R3 Compatible is a powerful, cost-efficient microcontroller board based on the ATmega328P SMD chip. Designed to match the classic Uno R3 in pin layout and functionality, it’s an ideal choice for makers, students, and engineers working on compact and robust embedded projects. Unlike the DIP version, this board features a surface-mounted microcontroller, which reduces production cost and increases durability—making it perfect for long-term or soldered installations. It includes 14 digital I/O pins (6 PWM-enabled), 6 analog inputs, a 16 MHz crystal oscillator, a USB interface for programming, and onboard voltage regulation. Thanks to its compatibility with the Arduino IDE and standard Uno R3 shields, it allows rapid prototyping for everything from basic circuits to complex IoT and automation systems. ✅ Key Features: • ATmega328P SMD version (Surface Mount Device)• 14 Digital I/O pins (6 PWM), 6 Analog inputs• Fully Arduino Uno R3 compatible (pinout & IDE support)• USB interface, power jack, and ICSP header• Compact, reliable, and cost-effective design• Built-in reset button and onboard regulators ��️ Common Applications: • Compact DIY electronics and smart devices• Embedded systems and real-time controllers• Home automation and sensor-based systems• Educational kits and programming workshops• IoT development and wireless monitoring projects
