FTDI UM232H-B USB to Serial/Parallel Break-Out Module is a development module for FTDI's FT232H Hi-Speed to Serial/Parallel interface converter. This single interface channel IC can be configured to transfer data over the following interfaces: UART, 245 FIFO, FT1248, I²C, SPI, and GPIO. The UM232H-B hardware is a breakout board that converts Hi-Speed USB 2.0 to a serial/parallel interface and connects the signals to a 2.00mm pitch 18pin female receptacle. No USB connector is used--instead this modules plugs directly into the USB host connector and the pads of the PCB make electrical contact with the electrical contacts of the host USB connector. All signals on these modules operate at +3.3V voltage levels, however all I/Os are 5V tolerant.
