Arduino UNO R3 SMD Version – ATmega328P Microcontroller Board (Without USB Cable)

🔌 Arduino UNO R3 SMD Version – ATmega328P Microcontroller Board (Without USB Cable)

The Arduino UNO R3 SMD Edition is a widely used microcontroller board built around the ATmega328P microcontroller in SMD (Surface-Mount Device) format. It offers the same functionality and pin layout as the classic UNO R3 DIP version but uses a surface-mounted chip instead of a removable one.

This version is fully compatible with the Arduino IDE, making it perfect for electronics students, DIY hobbyists, and prototyping professionals. It’s ideal for everything from basic LED blinking projects to advanced IoT systems.

Please note: This board does not include a USB cable. You will need a USB Type-B cable to connect it to your computer.
