RS485 to TTL Converter Module Serial Port UART Hardware Automatic Flow Control Module

The RS485 to TTL Converter Module with Hardware Automatic Flow Control is designed based on the MAX485 chip, a reliable choice for RS485 bus applications. This module supports both 3.3V and 5V power supplies and TTL levels, making it versatile for various applications. It can connect and identify up to 128 nodes on the RS485 bus and supports long-range bus communication.

  Features:  

1. Fully considered mine design for long-distance RS485 signal transmission, providing good anti-jamming and anti-interference effects when connected to ground.
2. Standard 2.54 pitch design for easy secondary development.
3. Built-in 120 ohm termination resistors, shorted R0 to enable the termination resistor.
4. Supports multi-machine communication, allowing access to up to 128 devices on the bus.
5. Hot-swappable module without signal dead phenomenon.
6. Large area of copper to prevent interference.
7. Compatible with 3.3V and 5.0V power supply and signal.
8. Absolute using imported chips for industrial design and anti-interference ability.
9. Can be used in industrial and harsh environments with a working temperature range of -40°C to +85°C.
10. Supports transmission distances of up to 1 kilometer (800 meters recommended for reliable performance, beyond 800 meters, repeaters are recommended).
11. Semi-hole pads and thin PCB design with a thickness of 0.8mm.
12. Includes RXD and TXD signal indicator lights to monitor send and receive status.

  Note:  

• Only one module should be used in the entire network.
• Supports 3.3V and 5.0V power supply, and RS485 signal is perfectly compatible with the automatic flow control module.
• Does not have "Receiving – launch" control, making it simple to use with serial port operations.

  Package Includes:  

• 1 x TTL To RS485 Module with Hardware Automatic Flow Control
