Arduino Uno R3 SMD

Description

The Arduino Uno R3 SMD is a cost-effective development board featuring the ATmega328 (SMD) microcontroller and CH340G USB-to-serial interface, making it a perfect alternative to the traditional Arduino Uno R3. This comprehensive kit ensures compatibility with the Arduino IDE and includes all essential components for beginners and advanced users.

With enhanced connectivity, including two rows of male/female pinholes and additional rows for wiring, the Arduino Uno R3 SMD supports seamless integration for diverse projects. The compact design replaces the DIP package with a flat package, optimizing space and functionality.
