This product achieves power and signal isolation between TTL and RS485 using a high-end isolated RS485 chip, providing strong anti-interference capabilities. It features a wide voltage input (3.0V~5.5V), ensuring compatibility with both 3.3V and 5.0V systems, and is compatible with both 3.3V and 5.0V communication signals. The product utilizes automatic flow control technology, automatically switching between transmit and receive directions, making it as simple to use as operating your MCU's serial port.
Features
1. Wide voltage supply design supports 3.0V to 5.5V input, offering strong adaptability and flexible usage
2. Compatible with 3.3V and 5.0V signal levels, seamlessly matching various modules to enhance system compatibility
3. Complete isolation between power and signals delivers outstanding performance with up to 16KV isolation voltage
4. Incorporates automatic flow direction control technology and industrial-grade protection design for strong anti-interference capability
5. Features lift-type terminals for the 485 port and standard 2.54mm pitch connectors for the TTL port, enabling easy installation. 6. Equipped with RXD and TXD transmission/reception indicator lights for real-time monitoring of communication status and operational visibility.

Important Notes
This transparent transmission module converts between TTL and RS485 signals. However, it is crucial to understand that RS485 operates in half-duplex mode. This communication method enables bidirectional data exchange but cannot transmit simultaneously in both directions. Communication must alternate between sending and receiving. Each end of the communication channel can function as either a transmitter or receiver, but data can only flow in one direction at any given time.
