TTL to RS485 Interface Converter based on MAX485 Chip (TTL to RS485 Converter Module)

A compact and reliable interface converter module based on the MAX485 chip, designed to establish communication between microcontrollers and peripheral devices using the industrial RS485 protocol. The board converts UART (TTL) signals into differential signals, which provides effective noise immunity and allows data transmission over distances of up to 1200 meters. The board features a convenient two-pin screw terminal for the communication line (A, B) and a standard row of pin headers for power and control signals (DI, DE, RE, RO). Features: Product type: interface module / TTL to RS485 converter (Interface Converter Board) Specifications: MAX485 chip, screw terminal block for lines A and B, power pins (VCC, GND) and logic pins (DI, DE, RE, RO), half-duplex communication support Purpose: converting UART/TTL logic levels of microcontrollers to the RS485 standard for noise-resistant data transmission over long distances
