Arduino UNO R3 Clone

Description

The Arduino Uno R3 Clone is a cost-effective alternative to the official Uno board. Built around the ATmega328P microcontroller, it offers the same functionality as the original, making it ideal for beginners and hobbyists. Most clones use the CH340 USB-to-serial chip instead of the ATmega16U2, requiring drivers on some systems. Fully compatible with the Arduino IDE, this board is great for education, prototyping, and DIY projects.
