There are a few. Marcel something on YouTube has a few videos explaining this particular module. The different audio codecs confused me a little at first. This module uses the Es8388 instead of AC101. There need to be more videos explaining the difference between the two codecs. Maybe an idea for a video particularly on the es8388 codec and setup.
