Waveshare USB to RS485 Serial Converter RS485 Communication Module 300-921600Bps Built-in ESD Protection Circuit

Waveshare USB to RS485 Serial Converter RS485 Communication Module 300-921600Bps Built-in ESD Protection Circuit

Details

Support USB to RS485 communication, using two imported chips, FT232RL and SP485EEN, high-speed communication, stable, reliable and good compatibility.
The onboard TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient spike voltage in the circuit, and it is anti-thunder and anti-static.
The onboard self-recovery fuse and protection diode can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve impact resistance.
There are 3 LED indicators on board for easy viewing of power supply and signal transceiver status.
Industrial-grade USB to RS485 converter, using two imported chip solutions FT232RL and SP485EEN, stable communication, suitable for various industrial control equipment or applications with high communication requirements.
