The Waveshare USB to 4CH RS485 Driver is an industrial-grade converter that allows seamless communication between USB ports and RS485 devices. This module is available in two options: Type A, a standard non-isolated version, and Type B, an isolated version that provides enhanced protection. Both types support baud rates ranging from 1200bps to 460800bps and offer ESD and surge protection, making them suitable for industrial and long-distance applications. They support multi-node communication, making them ideal for point-to-multipoint configurations in networked environments.
