Appendix A EVM Connector Descriptions

This appendix contains the connection details for each of the main header connectors on the EVM.

A.1 Analog Interface Connectors

A.1.1 Analog Input/Output Connectors

In addition to the analog headers, the analog inputs and outputs also can be accessed through alternate connectors, either screw terminals or audio jacks. The stereo microphone input is also tied to J6 and the stereo headphone output (the HP set of outputs) is available at J7.

Table A-1summarizes the analog input/output connectors available for Block A.
