TTL-RS485-ISO, Isolated TTL to RS485 Converter Module, Supports 3.3V and 5V Logic

The TTL-RS485-ISO is a robust and reliable converter module designed to convert TTL level signals (3.3V/5V) into RS485 differential signals with electrical isolation. Featuring onboard optocouplers and DC-DC isolation, this module ensures stable communication and protection for microcontrollers and other logic-level devices in industrial or noisy environments.

Key Features:

• Isolated TTL to RS485 bidirectional converter module
• Supports 3.3V and 5V TTL logic levels for wide MCU compatibility
• Integrated optocoupler and isolated power supply for signal integrity
• USB power or VCC pin input supported
• Onboard TX/RX LEDs for communication indication
• Compact PCB layout with terminal blocks for RS485 connection
