How to use an Arduino Speaker module with DFPlayer Mini? I've bought an Arduino speaker module. How should I connect the module, if I want to use it with DFPlayer Mini? The problem is that the speaker module has 3 pins: GND, VCC, and IN; though the DFPlayer Mini has 2 pins for connecting a speaker: SPEAKER + and SPEAKER -.
The DFPlayer already has an amplifier on it, so you can connect the speaker directly.
You can just leave out the board you bought from AliExpress, and only use the speaker.
