The FT232RL is a USB to Serial UART interface IC device. It is used for converting a USB port to Serial UART (Universal Asynchronous Receiver/Transmitter) interface. It is designed to be used with FTDI’s VCOM (Virtual COM) drivers, to easily add a RS232 like interface to any PC. It is also used in a wide range of industrial and consumer products, including: industrial PLCs, GPS receivers, medical instruments, automobile diagnostics equipment, and more. It can be used to support a wide range of serial protocols, such as RS-232C, RS-422, and RS-485. It provides an easy and seamless way to upgrade legacy RS232 devices, with little or no additional hardware or software.
