Waveshare USB to RS485 Serial Converter USB to 485 RS485 Communication Module FT232 Industrial Grade Board

Support USB to RS485 communication

Using original FT232RL, high-speed communication is stable, reliable and compatible

Onboard TVS (transient voltage suppression tube), which can effectively suppress surge voltage and transient spike voltage in the circuit, lightning protection and static electricity protection

Onboard self-recovery fuses and protection diodes can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve shock resistance

Three external LED indicators for easy viewing of power and signal transceiver status
