The USB-RS485-PCB is a USB to RS485 level serial UART converter PCB incorporating FTDI‟s FT232RQ USB to Serial UART interface IC device which handles all the USB signalling and protocols. The PCB provides a fast, simple way to connect devices with a RS485 interface to USB.

The USB-RS485-PCB contains a small internal electronic circuit board, utilising the FT232R plus a USB type-A connector.The PCB is USB powered and USB 2.0 full speed compatible. Each PCB supports a data transfer rate up to 3 Mbaud and supports the FTDIChip-ID™, with a unique USB serial number programmed into the FT232R. This feature can be used to create a security or password protected file transfer access using the PCB
