Waveshare FT232RL USB to RS232/RS485/TTL Module Interface Conversion Industrial Grade with Isolation

Support USB to RS232, USB to RS485, USB to TTL (UART) communication

Using original FT232RL, high-speed communication is stable, reliable and compatible

Onboard integrated power supply isolation can provide stable isolation voltage without additional power supply at the isolation end

Onboard integrated ADI magnetic coupling isolation, signal isolation, high reliability, strong anti-interference, low power consumption

Onboard TVS (transient voltage suppression tube), which can effectively suppress surge voltage and transient spike voltage in the circuit, lightning protection and static electricity protection

Onboard self-recovery fuses and protection diodes can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve shock resistance

Onboard automatic transceiver conversion circuit to ensure that the USB terminal and different interfaces can communicate quickly and stably without interfering with each other

Onboard TTL serial port 3.3V and 5V level conversion circuit, users can switch TTL communication level through switch

Aluminum alloy shell, oxidized matte treatment, CNC numerical control opening, firm and durable, exquisite workmanship

Three external LED indicators for easy viewing of power and signal transceiver status

High-quality USB-B and RS232 interface materials, smooth insertion and removal, solid and reliable
