A.2. Audio CODEC interface

The PB-A8 provides three stacked 3.5mm jack connectors on the rear panel that enable you to connect to the analog microphone and auxiliary line level input and output on the CODEC.

Figure A.2 shows the pinouts of the sockets. See Figure 3.3 for the connector location.


A link (LK3) on the baseboard enables bias voltage to be applied to the microphone.
