ReSpeaker Core v2.0 external audio amplifier

Post by peder.alm » Fri Jun 14, 2019 3:38 am

Hi

I have a ReSpeaker Core v2.0. I would like to add an external audio amplifier. Is this possible and how do I do that? Using headphone jack or JST2.0? Do you recommend any ampifier module?

And is it possible to ge a schematic over the ReSpeaker Core v2.0 audio part (headphone amplifier and the class D amplifier)?
