Product Description: This MAX485 module enables reliable TTL-to-RS-485 signal conversion, designed for long-distance industrial communication (up to 1200m at 9600bps). It operates on 5V DC, compatible with PLCs, industrial sensors, and microcontrollers (Arduino, STM32). Built-in ESD protection (±15kV) and overcurrent safeguards ensure stability in harsh factory environments, while the compact FR4 PCB design fits seamlessly into industrial control panels.
