LORDWORLD USB to RS485 Converter FT232RL Development Board

SKU CH-45FF-5YES9

Converts USB to RS485 using an original FT232RL chip with TVS, self-recovery fuse and three status LEDs

  • Reliable USB to RS485 link via original FT232RL chip
  • Surge and static protection from onboard TVS diode
  • Self-recovery fuse guards against over-current and over-voltage
  • Stable voltage output maintained by protection diodes
  • Three status LEDs show power and transceiver activity

USB-to-RS485 converter with FT232RL

This industrial-grade board converts USB signals to RS485 for reliable serial communication. It uses an original FT232RL chip for stable data transfer and broad driver compatibility. Built-in protection circuits guard against voltage spikes and over-current events. Three status LEDs show power and transceiver activity at a glance.

Makers and engineers needing rugged serial links

The board suits developers adding RS485 to PCs or embedded systems where noise immunity matters. It is not for designs that require USB-to-RS232 or USB-to-TTL level conversion. Buyers who need galvanic isolation should look at a different module. Projects demanding multiple serial ports will need additional hardware.

FT232RL chipset defines driver support

The original FT232RL controller determines which operating systems and baud rates are supported without extra firmware. On-board TVS diodes, a self-recovery fuse and protection diodes handle surge suppression and over-voltage safety. These circuits set the electrical limits for the RS485 transceiver.

Questions about this item

Will the FT232RL chip on this converter work with my existing RS485 sensors and PLCs?

The board uses an original FT232RL chip for USB to RS485 communication, providing stable and reliable data transfer with broad driver compatibility for legacy Modbus and industrial devices.

How do I confirm the link is active after wiring the converter?

Three onboard LEDs show power, transmit and receive status so you can see traffic flowing immediately after connection.

Does the package include a USB cable and terminal-block plugs for the RS485 side?

The development board itself is supplied; a USB cable and any screw-terminal connectors for the RS485 lines are not included and must be sourced separately.
