UART TTL to RS485 Two-Way Converter – Bi-Directional Serial Interface for RS485 Communication

The UART TTL to RS485 two-way converter allows bidirectional data communication between microcontrollers (like Arduino, ESP32, STM32, Raspberry Pi) and RS485-compatible devices. It supports Modbus RTU protocol, making it ideal for industrial sensors, automation systems, and IoT applications.

Designed for stable, long-distance communication up to 1200 meters, this converter features automatic data direction control, eliminating the need for manual switching.

Key Features:

• Converts UART TTL to RS485 (two-way communication)

• Supports 3.3V and 5V logic levels

• Built-in automatic direction control circuit

• Baud rate: up to 115200 bps

• Communication distance: up to 1200 meters

• Compact and easy to integrate with Arduino, ESP32, STM32

• Ideal for Modbus RTU and RS485 networks

Applications:

• Connecting RS485 sensors (e.g., NPK, EC, pH) to ESP32

• Modbus RTU-based smart agriculture

• Industrial automation and control

• RS485-based IoT projects in Bangladesh

The UART TTL to RS485 converter is a dependable interface for long-distance and noise-resistant serial communication in embedded systems.
