Figure 1 shows the schematic of the evaluation board, and
Figure 2 shows the flex board layout. See the respective
microphone data sheets for complete descriptions and
specifications of the microphones. Note that the layout for
the EV_ICS-40180-FX differs slightly from what is shown in
Figure 2 because of this part’s different package footprint,
but the routing of the three signals is consistent.
