Arduino Uno R3 SMD Development Board – ATmega328P Microcontroller for Robotics, IoT & DIY Electronics

The Arduino Uno R3 SMD Board is a versatile and beginner-friendly development board powered by the ATmega328P microcontroller in a Surface Mount Device (SMD) package. It provides the same performance and compatibility as the standard Arduino Uno while using a permanently soldered microcontroller for improved durability.

With 14 digital I/O pins, 6 PWM outputs, 6 analog inputs, and a 16 MHz clock speed, the board is ideal for programming, robotics, home automation, sensor interfacing, and embedded system development. It is fully compatible with the Arduino IDE and supports thousands of libraries and modules, making it an excellent choice for learning and prototyping.
