Waveshare CH343G USB TO RS232/485/TTL Interface Converter, Industrial Isolation

Waveshare CH343G USB TO RS232/485/TTL Interface Converter, Industrial Isolation. Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal. unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption.

Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning proof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shock resistance.

Features:
A fully automatic transceiver circuit with no delay ensures the USB port communicates with different interfaces fastly and stably, without interfering with each other
Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch
Aluminum alloy enclosure with sandblasting and anodic oxidation, CNC process opening, solid and durable
3 LEDs for indicating the power and transceiver status
High-quality USB-B and RS232 connectors, smoothly plug/pull
