ATMEGA328-PU 8bit AVR Microcontroller, 20MHz, 32 kB Flash, 28-Pin PDIP With Arduino Bootloader

🌟 Product Description

The Arduino UNO SMD is a microcontroller board based on the ATmega328P in an SMD package, offering the same features as the classic UNO but in a more compact layout. It’s widely used in robotics, CNC controllers, and embedded electronics for rapid prototyping, sensor interfacing, and control applications.
