The System Demonstration Platform Breakout Board provides a means to monitor each of the SDP’s 120 pin connector’s signals individually. Each of the 120 signals on the connector interface is exposed on the breakout board using through hole probe points.
The SDP Breakout Board has a 120 pin receptacle connector for connecting to the SDP boards 120 pin header. It also has a 120 pin header connector to allow a daughter board designed for the SDP to be connected onto the Breakout Board. In this way the Breakout Board can simultaneously connect to an SDP and a daughter board allowing the user to monitor the signals travelling between the two boards.
The SDP breakout board contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused SDP boards in the protective shipping package.
When removing the SDP board from the package, handle the board carefully to avoid the discharge of static electricity, which can damage some components.
