TTL to RS485 Converter Module (MAX485) | UART Serial Adapter

TTL to RS485 Converter Module based on the MAX485 transceiver, designed to convert UART (TTL) serial signals to robust RS485 differential communication for long-distance, noise-resistant data transfer.

• Chipset: MAX485 (RS485/RS422 transceiver)
• Interface: UART TTL (DI/RO) + RS485 A/B screw terminal
• Power: 3.3V–5V compatible (VCC & GND)
• Mode: Half-duplex RS485 (DE/RE control)
• Use Cases: MODBUS RTU, industrial automation, PLC communication, Arduino/ESP32/Raspberry Pi serial networks
• Features: Differential signaling, long-distance transmission, improved noise immunity

Note: Connect DI to TX, RO to RX. Control DE/RE pins for transmit/receive (some setups can tie DE and RE together).
