I want to use DFPlayer to play an audio file without loading the output pins with a speaker. Those pins will be used as Line-Out to feed an external amplifier.
I need to know the current draw from a 5V supply in that configuration. I'd simply measure it myself but unfortunately, I don't have a DFPlayer module handy at the moment. I read somewhere that it draws about 15mA when idle with an empty microSD card slot, and more when playing an audio file from an SD card.
Could someone please provide the information I need, that is, the current consumption when playing an audio file but without a speaker at the output?
