I’m waiting for those from the mail:
PAM8403 with this board format:
X9c103S with this board format:
I was planning to use the X9c103S as ESP/Arduino controllable potentiometer to mix multiple inputs for the PAM8403. I will connect the audio out of some audio source, to the VH pin and the Line in of the PAM to the VW. My question is, should I connect the VL to ground? And also, should I add anything between the 2 units???
I prefer to ask questions, and get answers, than experiment and burn my audio, in this case.
So any comments? Any one has experimented the 2 kinds of modules together? Maybe it would be better with the X9c104S?
Oh, one more thing, there seam to be a place to put a capacitor at the back, C4, any one has an idea of the required value?
