UM232H-B USB to
Serial/Parallel Break-Out
Module
UM232H-B is a multiple-interface Hi-Speed USB to
UART, 245 FIFO,
FT1248, I
2
C, SPI and GPIO
break-out module.

Introduction
The UM232H-B 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, I
2
C, SPI and GPIO.
For detail on FT232H, refer to the
FT232H
datasheet.
1.1
Features
This hardware is a breakout board that
converts Hi-Speed USB2.0 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
makes 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.
