Waveshare Industrial USB TO RS485 Bidirectional Converter, Onboard original CH343G, Multi-Protection Circuits

Introducing the Waveshare Industrial USB TO RS485 Bidirectional Converter, featuring the onboard Original CH343G chip for enhanced stability and compatibility. Equipped with multi-protection circuits and SP485EEN chips, this converter ensures reliable performance in industrial settings.

Key features include a built-in lightning proof tube, resettable fuse, ESD protection circuits, and TVS protection circuits, providing comprehensive protection for your devices.

The converter seamlessly converts USB signals into balanced differential RS485 signals, ensuring stable transmission rates ranging from 300bps to 3Mbps. With RS485, it offers a transmission distance of approximately 1.2km, while USB transmission reaches up to 5 meters.

The CH343G chip acts as a USB bus adapter, converting USB to a high-speed asynchronous serial port. It supports automatic identification and dynamic self-adaptation of communication baud rates up to 115200bps, while also providing commonly-used MODEM contact signals to expand asynchronous serial ports for computers. This versatile chip allows for direct upgrading of common serial devices or MCUs to a USB bus interface.

Features:

1. Support USB to RS485 bidirectional conversion
2. Fast communication, stable and reliable, better compatibility
3. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic
4. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
5. 3 LEDs for indicating the power and transceiver status
