What is the part number and manufacturer name of the 20-pin Connect ME socket header on the programming board that comes with the Connect ME Integration and Development Kits?

4. From the CLP Series Overview page, at the top of the page is a link to "Build A Part Number". Select this link.
5. From this page you can select the options you desire and validate your generated part number.
