📌 Overview of Arduino UNO (SMD)

The Arduino UNO (SMD) is a widely used microcontroller board based on the ATmega328P, designed for IoT, Arduino, and DIY projects. It offers the same features as the classic UNO, but uses a surface-mount (SMD) version of the chip, making it more compact and cost-effective. Moreover, it remains fully compatible with the Arduino IDE and countless open-source libraries, which makes it an excellent choice for both beginners and professionals.

With 14 digital input/output pins, 6 analog inputs, and USB connectivity, the board provides a versatile platform for prototyping. As a result, the Arduino UNO (SMD) is highly suitable for robotics, embedded systems, and smart devices. In addition, its strong community support ensures that you can always find tutorials, guides, and resources to accelerate your learning.
