Features
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, lightningproof & 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
