TTL-RS485 SP485/MAX485 5VDC

This TTL to RS485 converter module allows microcontrollers (Arduino, Raspberry Pi) to interface with long-distance serial communication networks. It features a transceiver chip compatible with the MAX485 or SP485 standards, ensuring robust and reliable data transmission for industrial and home automation applications.

The module operates at 5VDC and supports half-duplex communication. The RE (Receiver Enable) and DE (Driver Enable) pins are typically tied together to control the direction of data flow. Perfect for connecting multiple devices on a single RS485 bus.
