Connect your TTL and RS485 devices with this versatile SCM TTL to RS485 Converter and 485 to UART Serial Port Module. Designed for seamless serial port communication, this module is equipped with automatic flow control for smooth data transfers, eliminating the need for manual "Receive-Transmit" control. It’s perfect for projects that require reliable, long-distance communication in industrial or harsh environments.

Features:

• Wide Voltage Compatibility: Supports both 3.3V and 5.0V power supplies and signals, ensuring flexibility with various microcontrollers and development boards.
• Automatic Flow Control: Handles data transmission automatically, making it as simple as plug-and-play with your serial interfaces.
• Industrial-Grade Design: Built with high-quality imported chips, this module features robust anti-interference and lightning protection for reliable performance, even in demanding field conditions.
• Extended Temperature Range: Operates smoothly between -40°C to +85°C, making it ideal for industrial applications.
• Long-Distance Communication: Supports transmission distances of up to 1 kilometer (recommended up to 800 meters for optimal performance, use repeaters beyond 800 meters).
• Compact, Versatile Form Factor: With a semi-hole design and a 0.8mm thick PCB, this module can be easily integrated into projects either as a picture board or with soldered terminals.
• Hot-Swappable: Safe to use with hot-swapping; the signal remains stable without any interruption.
• RXD and TXD Indicators: Built-in LED indicators for easy monitoring of data transmission and reception.
• Multi-Device Support: Enables communication between up to 128 devices on the same bus, making it ideal for multi-machine setups.
• Built-in 120 Ohm Termination Resistor: Includes an optional 120 ohm matching resistor (enabled by shorting R0) to improve communication reliability over long distances.
• Standard 2.54mm Pitch: Easy integration with breadboards or other prototyping platforms.
