Arduino UNO R3 CH340G ATMega328P

Arduino Uno R3 SMD Clone

The Arduino Uno R3 SMD Clone is a highly popular development board widely used by beginners and hobbyists. This clone version features the CH340 USB-to-serial converter IC and an ATmega328 microcontroller pre-installed as an SMD (surface mount device) with the Arduino bootloader. Unlike some other clone variants, the microcontroller is fixed on the board, making it cost-effective and reliable.

This board offers all the functionality of the original Arduino Uno R3 (REV3) and comes bundled with a USB cable for easy connection.
