MAX485 TTL to RS-485 Module – Serial Communication Converter
The MAX485 TTL to RS-485 Module is a compact, low-power transceiver designed to convert TTL serial signals (Arduino, ESP32, PIC, STM32) into RS-485 differential signals. RS-485 is widely used for long-distance, noise-resistant communication in industrial, automation, and IoT systems.
Its small size, low power consumption, and stable performance make it a popular choice among engineers, students, and hobbyists in Kenya, especially for building reliable multi-device communication networks.
Key Features:
TTL to RS-485 Conversion: Enables long-distance serial communication up to 1200 meters.
Half-Duplex Communication: Uses only two wires (A & B) for bidirectional data transfer.
Low Power Consumption: Built around the high-efficiency MAX485 IC.
Wide Compatibility: Works with Arduino, ESP8266, ESP32, Raspberry Pi, PIC, STM32, and industrial controllers.
Anti-Interference: RS-485 differential signaling provides stability in noisy environments.
Screw Terminals: Easy wiring for RS-485 A/B terminals.
Commonly used in Kenya: Ideal for automation, remote sensors, security systems, and Modbus setups.
