From the project
2in4out ADAU1701 Board with selectable 2 EEPROMs, SMD resisitors, ThtoughHole Ele-Caps.
This PCB design was inherit from FreeDSP SMD. Canages and improved in many points. - Unity Gain I/O - Selectable boot EEPROM - Power ON/OFF Mute - Buffered I2S I/O Headers
Errata: R49 47k ohms --> 4.7k ohms (Need to pull-up strong)
