The TTL-232R-3V3-WE is an USB to UART cable with +3.3V TTL level UART signals incorporating FT232RQ USB to serial UART interface IC device. The FT232RQ handles all the USB signalling and protocols. The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB. The cable contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated into the USB connector end of the cable. The USB side of the cable is USB powered and USB 2.0 full speed compatible. The cable is 1.8m long and supports a data transfer rate up to 3Mbaud. The TTL-232R-3V3-WE 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 cable. The TTL-232R cables require USB drivers, which are used to make the FT232R in the cable appear as a virtual COM port (VCP).
