Waveshare USB to RS232/485/TTL Interface Converter Communication Module (CH343G Chip) w/ Isolation

Advantages:
* Industrial-grade isolated USB converter
* USB to RS232/485/TTL
* Stable transmission
* Applicable to multiple devices
* Compatible with multiple systems

Features:
* Original FT232RNL chip or original CH343G chip. High-speed communication is stable, reliable and compatible
* On-board integrated power isolation provides a stable isolation voltage. No additional power supply is required for the isolated end
* On-board integrated digital isolation enables signal isolation. High reliability, strong anti-interference, and low power consumption
* On-board TVS (Transient Voltage Suppressor) can effectively suppress surge voltage and transient spike voltage in the circuit, lightning protection and anti-static
* On-board resettable fuse and protection diode ensure stable current and voltage output, with over-current and over-voltage protection, improving shock resistance
* On-board automatic transceiver conversion circuit ensures that the USB terminal and different interfaces can communicate quickly and stably without interfering with each other
* On-board TTL serial 3.3V and 5V level translation circuits: users can switch TTL communication levels
* Aluminum alloy shell with oxidized matte treatment and CNC numerical control opening. It is strong and durable, and the craftsmanship is exquisite
* 3 external LEDs allow users to check the power supply and signal transmission status
* High-quality USB-B and RS232 interface materials, smooth plugging and unplugging. Rugged and reliable
