CODEC Motherboard
1 Hardware Overview
All instructions in this guide require some familiarity with the physical layout of the motherboard
and daughter cards. This information is introduced as needed, so it is not necessary at first to
memorize or understand the complete layout and functions of the hardware.
There are various daughter card can be used for the same motherboard. They are NAU8812,
NAU8814, NAU8810, NAU88C10, NAU8811, NAU8820, WAU8822, NAU8822L, NAU88C22,
NAU8401, NAU8402, NAU8501, and NAU8502.
However, to get started, a few basic inputs and outputs must be noted. The USB connector and
external audio inputs/outputs are highlighted in this section.
Control and power are supplied via the USB connector. When first learning how to use this
system, it is recommended to choose a simple audio input and output combination. One example
would be to input audio from a line level source such as a CD-audio player into the Aux inputs,
and to listen to the output on the headphone connector.
