FTDI Chip USB To UART Development Board

The FTDI Chip USB to UART development board is a miniature kit that uses FTDI’s FT232RQ, which is the latest device to be added to FTDI’s range of USB UART interface integrated circuit devices. It is a USB to serial UART interface with optional clock generator output and with asynchronous and synchronous bit bang interface modes. The USB to serial interface designs uses the FT232RQ and have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. Also, there is a unique number burnt into the device during manufacture and is readable over USB. This forms the basis of a security dongle, which can be used to protect customer application software from being copied.
