CH340G USB to Serial Converter

CH340G USB to Serial TTL Converter (with 3.3V/5V Switch)

Looking for a reliable way to connect your microcontroller projects to your PC? The CH340G USB to Serial TTL Converter is a compact, cost-effective solution that bridges your USB port and serial devices with ease. Whether you’re debugging, programming, or just tinkering with Arduino, Raspberry Pi, or other microcontrollers like AVR, PIC, or 8051, this little module is up to the task.

At the heart of the converter is the CH340G chip, known for its stability and compatibility across a wide range of systems. Despite being more budget-friendly than FTDI-based alternatives, it delivers excellent performance for most development environments—including seamless integration with the Arduino IDE.

Key Features:

• Dual Voltage Output: Easily switch between 3.3V and 5V logic levels using the onboard jumper, making it suitable for a wide range of devices.
• Plug and Play: Once the drivers are installed, the module appears as a standard COM port—ready to use with popular terminal programs and IDEs.
• Universal Compatibility: Works with a long list of Windows versions, from Windows 98 all the way up to Windows 8 (32 & 64 bit). Also supports USB 1.1, 2.0, and 3.0 ports.
• Versatile Communication: Supports RS232, RS485, RS422, IRDA SIR infrared communication, and common MODE contact signals.

Ideal For:

• Uploading code to microcontrollers
• UART communication debugging
• Using serial monitors
• Learning and prototyping with embedded systems
