**Product Introduction**

This product features the latest mainstream CH343P chip, capable of a maximum data rate of 6Mbps. It offers enhanced driver compatibility—requiring virtually no drivers in most cases, or allowing for instant installation of official drivers. By integrating a high-end isolated RS485 chip, the module achieves complete power and signal isolation between the TTL and RS485 interfaces, ensuring strong resistance to interference. The product utilizes automatic data flow control technology, allowing for automatic switching between transmission and reception directions for simple, hassle-free operation. Supported Baud Rates: 10 to 256,000 bps.

**Important Notes:**

This transparent transmission module facilitates the mutual conversion between USB-to-TTL signals and RS485 signals. However, users must understand that RS485 operates as a *half-duplex* communication protocol. While this communication method enables bidirectional data exchange, it cannot transmit data in both directions *simultaneously*; transmission must occur in an alternating, sequential manner. In other words, either end of the communication channel can function as a transmitter or a receiver, but at any given moment, data can only flow in one direction.
