Arduino Uno R3 CH340G ATmega328P SMD Development Board

Arduino Uno R3-Compatible CH340G Development Board

This Uno R3-compatible development board combines an ATmega328P microcontroller in an SMD package with a CH340G USB-to-serial interface. It follows the familiar Arduino Uno R3 pin layout, making it suitable for learning electronics, breadboard prototyping, robotics, sensor projects and embedded development.

The board can be programmed through its USB Type-B connector using the Arduino IDE. Depending on the computer and operating system, a CH340 USB driver may be required. This is a compatible development board and is not an official Arduino-branded product.

Key Specifications

Compatibility

• Programmable with the Arduino IDE by selecting the Arduino Uno board profile.
• Compatible with many shields and modules designed for the standard Uno R3 header layout.
• Supports common sensors, displays, motor drivers, relay modules and communication modules when their voltage and current requirements are suitable.
• Uses a CH340G USB interface; install the appropriate CH340 driver if the board is not detected automatically.

Typical Applications

• Arduino programming and electronics education
• Robotics and motor-control prototypes
• Sensor monitoring and data acquisition
• Home automation and IoT experiments
• LED, display and relay-control projects
