Hi jieverson!
The Daisy Seed and the Daisy Patch Submodule (AKA the Patch SM, which powers the Daisy Patch.Init()) have different pin names.
I recommend taking a look at the pinout diagram for each.
And this Patch.Init() design file will show you which of the SM pins are used.
With all these in mind, I recommend looking at the .json file for the Patch.Init() again. And then I recommend referencing json file for boards that are powered by Seed, for example pod.json.
And I made a guide on creating custom json file for the Seed: Quick Guide on Setting Up a Custom JSON File for pd2dsy & Oopsy!
So all in all, you would need to make a separate json file for your new module that is powered by the Seed.
I hope this helps!!
