I found WCD9335 is 0.35mm pitch BGA. It's too bad for prototype. Do Intrinsyc support other CODEC? Or can I buy U1800 typed module from Intrinsic?
Yes, Intrinsyc does sell the audio codec module U1800 located on the uSOM 820 carrier board. Please contact firstname.lastname@example.org for more information. I have also passed your information to our account manager located in Taiwan. He will contact you for more information.
That is great news!! Thanks a lot.
I found WCD9335 has two interrupt pin: CODEC_INT1_N and CODEC_INT2_N. Since I don't use VBAT_ADC_IN to monitor battery voltage, did I still need those pin?
If you are not enabling the VBAT monitor feature, please do the following on the module:
Got it and thanks!
