They stack. basically the whole setup is a three layer sandwich. search for it on adafruit.com.

I would also add that this is still a work in progress and I am having issues getting things to work properly.

OK, minor update. I worked with the alorium manufacturer and we identified a bug in their servo librar that was completely unknown to them until now. The board currently only has options for controlling 4 servos. I need about 10 for the final end game setup I am shooting for.

I am also still looking at porting things over to circuit python.

The components are there and this would also enable a direct plug-in for a raspberry pi which has a fair bit more oomph to function. The pi can directly play the audio so that would remove the vs1053 board in that setup, but I would have to figure out a low power auto shutdown sequence trigger as well. (The raspberry pi sdcards have a chance of corruption if improperly being shut down.) The more I improve the more complications I run into.
