Product Overview

The TTL-232RG-VSW3V3-WE is an USB to UART cable with +3.3V TTL level UART signals incorporating FT232RQ USB to serial UART interface IC which handles all the USB signalling and protocols. The cables provide a fast, simple way to connect devices with a logic level serial interface to USB. It contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated into the USB connector end of cable. The other end of cable is wire ended. The cables can be used for TTL or interface logic over a range to voltage levels. The USB side of the cable is USB powered and is USB 2.0 full speed compatible. The cable is 1.8m long and supports a data transfer rate up to 3Mbaud. It 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. This cables require USB drivers, which are used to make the FT232R in the cable appear as a virtual COM port.
