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.

Figure 4.1 – Module Pin Out
Figure 4.1 illustrates the signals available on the signal pads. The top figure shows the pinout when the
module is viewed from the top side. The bottom figure shows the pinout when the module is viewed from
the bottom side.
Note:
Take care when plugging module into a deep recessed USB port, it may damage component C1.
