This appendix contains the connection details for each of the main header connectors on the EVM.
In addition to the analog headers, the analog inputs and outputs also can be accessed through alternateconnectors, either screw terminals or audio jacks. The stereo microphone input is also tied to J6 and thestereo headphone output (the HP set of outputs) is available at J7.
Table A-1 summarizes the analog input/output connectors available for Block A.
