Way to schematic diagram

Creating a bluetooth speaker using esp32

I started with creating best and affordable schematic diagram. It takes me about some time . After it I noticed some issues and solving that the final schematic diagram is ready it take me 1.5h approximately.
I create this project after my schematic diagram, because I am not sure to take that it. If the schematic diagram complete then I decided to create a project here.
