AUTO-DIRECTION CONTROL: Onboard auto-direction circuit automatically manages RS485 bus transmission, eliminating the need for manual GPIO toggling and simplifying your software development.
INDUSTRIAL-GRADE RELIABILITY: Built with original imported chips for stable, reliable performance in harsh industrial environments with electromagnetic interference.
WIDE VOLTAGE COMPATIBILITY: TTL side compatible with both 3.3V and 5V logic levels, making it easy to interface with popular microcontrollers like Arduino, STM32, and ESP8266.
HIGH-SPEED DATA RATE: Supports baud rates up to 2M bps, ideal for high-speed data acquisition and industrial fieldbus applications.
LONG-DISTANCE COMMUNICATION: Standard RS485 interface supports transmission distances up to 1200 meters with excellent noise immunity for reliable operation in noisy environments.
