I am not familiar with I2S — did you mean I2C?
I’m not sure? Still learning here. Did the picture make any sense to you? From what I’ve read, The rev 1 pi used an 8-pin header (P5 in the image), which is referred to as I2s. The ver. 2 incorporates this pins into the gpio. Most newer cards just mount directly to the gpio, which obviously is not an option.
The audio out is only 11 bit. Looking for a little better. Just because😁
