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.
