FTDI TTL-232RG USB to TTL serial UART converter cables build upon the existing FTDI family of USB to TTL cables by offering new versions to support an extended variety of voltage I/O levels. FTDI TTL-232RG cables features the FT232R USB 2.0 to UART converter IC with associated circuitry integrated within the cable USB connector. The FT232R manages the complete USB protocol within the device, meaning that no user knowledge of USB is required. These FTDI cables are aimed at providing USB connectivity within applications with serial UART ports. TTL-232RG cables provide a fast and simple method for enabling USB connectivity in applications with minimal changes to existing user interface.
