●Summary of Change:Change uEZGUI-EXP-DK BOM for incorrect capacitors on analog audio signal going into Wolfs on Audio codec
●Reason for Change: The first 25 prototype assemblies were loaded with incorrect C32 and C38 capacitor values which caused a very specific audio circuit option not to work correctly.
●Detailed Description of Change:Change both C32 and C38 to 220pF. This corrects the DAC input into the Wolfs on codec which will allow analog playback into the headphone connector when I²S Audio is not utilized. Most use cases involve either using the I²S Audio with Wolfson or direct DAC output to the onboard amplifier circuit. Therefore,this affected feature is only used in special configurations.
