Uno R3 CH340G ATmega328p Development Board - Compatible with Arduino (Without Cable)

Uno R3 CH340G ATmega328p Development Board - Compatible with Arduino

This Uno R3 CH340G Development Board provides the full functionality and robust ecosystem of the original Arduino Uno R3 at an affordable price point. It utilizes the industry-standard ATmega328p microcontroller, offering 32 KB of Flash Memory and a 16 MHz clock speed, making it the perfect platform for beginners and rapid prototyping in robotics, IoT, and control systems.

The primary difference from the official Uno is the replacement of the original USB-to-Serial converter chip with the popular CH340G. This change maintains flawless compatibility with the Arduino IDE (though a small driver installation may be required) while significantly reducing cost. The board is designed with the exact Uno R3 footprint, ensuring compatibility with the vast array of existing Arduino shields. Power can be supplied via the USB port for programming or a standard 7V to 12V DC adapter via the barrel jack.
