• Support USB to RS485 bidirectional conversion
• Onboard Original FT232RL and SP485EEN chip. Fast communication, stable and reliable, better compatibility
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic
• Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
• 3 LEDs for indicating the power and transceiver status
