The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an o amplifier (such as 3.7W stereo amp) if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin directly to the microcontroller ADC pin.For o-reactive projects, we suggest using an FFT driver library which can take the o input and translate it into frequencies.Colour: purpleMaterial: PC +...
