10X USB to RS485 Serial Converter RS485 Communication Module 300-921600Bps Built-in ESD Protection Circuit FT232RL + SP485EEN

10X industrial-grade USB to RS485 converter supporting 300-921600Bps data rates. The module uses a two-chip design—FT232RL and SP485EEN—to provide high-speed, stable and reliable serial communication with broad compatibility for industrial control and other demanding applications. Protection components include an onboard self-recovery fuse and a protection diode to stabilize current and voltage, guard against overcurrent and overvoltage, and increase resistance to impact. A transient voltage suppression tube (TVS) is fitted to suppress surge and transient spike voltages and provide anti-static/ESD protection. Three LED indicators on the board allow quick visual checks of power and signal transceiver status.
