components of dfminiplayer module

does anyone know which SMD capacitors DFminiplayermodule use?

I didn't see anywhere that DFRobot posted an actual schematic of the DFPlayer Mini. I'd suggest googling the mp3 decoder chip that your module uses. For example, some use the YX5xxx series chips (like the YX5200). Maybe you can search for those and see what the datasheet states is required.
