Product details

The Arduino Uno R3 (CH340) is a reliable and cost-effective clone of the original Arduino Uno, featuring the same ATmega328 microcontroller and full software compatibility with the official Arduino IDE.

This board includes the CH340 USB-to-serial converter, providing stable communication between your PC and the microcontroller. Although it uses an SMD version of the ATmega328 instead of the original DIP package, performance and functionality remain identical.

Perfect for students, hobbyists, and developers, this Uno R3 clone offers the same functionality as the official version at a more affordable price — making it an excellent choice for learning, prototyping, and DIY electronics projects.
