This document is the user guide for the EVAL-ADMP441Z daughter board, which works with the EVAL-ADMP441Z-FLEX board and the System Demonstration Platform (SDP) to evaluate the ADMP441 I2S MEMS microphone. The evaluation kit allows users to stream two channels of audio from two microphones to a PC over a USB connection without requiring additional drivers or software.
