Introduction
UMFT201XB, UMFT220XB, and UMFT230XB breakout
modules utilize FTDI’s FT201XQ, FT220XQ, and
FT230XQ chips, respectively, to convert USB to serial
or parallel interfaces. . These modules support the
following popular interfaces:

UMFT220XB bridges from USB to a user chosen,
parallel bit interface, FTDI’s FT1248/SPI. Note: 2
out of the 4 I/0 lines are available for this module.

Features
This module is a breakout board with a low
profile. It converts USB2.0 Full-Speed to a
serial interface and connects the serial
signals to a 2.54mm (0.1”) pitch 10pin
female receptacle. The boards do not use a
USB connector, but instead the modules
plug directly into the USB host connector
and the pads of the PCB makes electrical
contact with the electrical contacts of the
USB connector.
All serial interfaces on these modules
operate at +3.3V voltage levels, however all
I/Os are 5V tolerant.

Signals and Configurations
For all three modules, CN1 connects directly to a USB host or HUB port, or can be connected to a USB
extension cable. This connects the USB data signals, 5V USB Bus power and GND. When connecting these
modules to a USB host or HUB the USB signal pads should be facing upwards, and when connecting to
vertical connector the USB signal pad should be facing right. If the module is plugged in the wrong way,
no contact will be made between PCB and HUB, no damage will occur from plugging the module in upside
down.
