Compared with CH340, CH343G has better compatibility, faster transmission rate, more accurate fault detection, and lower power consumption! This module has strong compatibility and stability, and can easily realize the conversion between USB and RS232, RS485, RS422, and TTL interfaces to meet the communication needs of various devices in different scenarios. At the same time, the module can select 5V/3.3V/1.8V/1.2V levels, and users can flexibly choose according to their needs to adapt to different devices and application scenarios. The product features are summarized as follows:1. High integration: Four-in-one design, integrating RS232, RS485, RS422, and TTL four interfaces, saving space and simplifying wiring.2. Rich interface resources: Provides a variety of interfaces such as DB9 male terminal blocks to meet the connection needs of different devices. And it uses the Type-C interface to connect to the PC, which is more versatile.3. Lightning and anti-static design: effectively protect the module from external interference and ensure stable and reliable communication.4. Power isolation: built-in power isolation module can realize the connection between different circuits, prevent current transmission, and reduce electromagnetic interference.5. Strong compatibility: this module can choose four different TTL levels of 5V/3.3V/1.8V/1.2V, which can adapt to more devices, and the voltage can be output as VOUT interface to power external devices.6. Wide application: suitable for industrial control, communication equipment, security monitoring, Internet of Things and other fields, to meet the communication needs in various complex environments.
