CH343G USB to UART Converter Module

Overview

The CH343G USB to UART converter module is designed for seamless communication between USB and serial devices. This advanced module supports a wide range of operating systems and offers enhanced data transfer rates, making it an essential tool for developers and engineers working with microcontrollers.

Key Features

• Advanced Chip Technology: Utilizes the latest CH343G chip, providing superior data rates of up to 6 Mbps compared to its predecessor, the CH340G. It also accommodates multiple serial port IO levels (5V / 3.3V / 2.5V / 1.8V).
• Broad Compatibility: Compatible with various operating systems including Mac, Linux, Android, Windows (7/8/8.1/10/11), ensuring versatility in application.
• Robust Protection Mechanisms: Equipped with an onboard resettable fuse and transient voltage suppressor that safeguard against overcurrent and overvoltage conditions while enhancing shock resistance for stable communication.
• IO Protection Circuits: Features integrated IO protection circuits that further ensure reliable performance by preventing damage from surges or static electricity.
• TTL Level Switching: Onboard pins allow users to select between 3.3V or 5V TTL communication levels based on their project requirements.
• Durable Design: Constructed using a double-sided black immersion gold process which not only enhances durability but also provides an aesthetically pleasing finish.

Indicator Lights

• PWR Indicator: Illuminates when power is detected from the USB interface.
• RXD Indicator: Activates when data is received from the device interface.
• TXD Indicator: Lights up during data transmission from the USB.
