UM232H-B: USB to UART, SPI, I2C, 245 FIFO, FT1248


The UM232H-B is a development module for FTDI’s FT232H Hi-speed to serial/parallel interface converter. This single channel IC can be configured to transfer data over the following interfaces: UART, 245 FIFO, FT1248, I2C, SPI, and GPIO.

For detailed information on the FT232H, refer to the FT232H datasheet.

This hardware is a breakout board that converts high-speed USB2.0 to a serial/parallel interface and connects the signals to a receptacle. No USB connector is used, instead this module plugs directly into the USB host connector and the pads of the PCB make electrical contact with the host USB connector.

All signals on this module operate at +3.3 V voltage levels, however all I/Os are 5 V tolerant.
