Short audio playback on Nano33BLE using flash

Did you try the Demo?

It says you can test the concept with earbuds.

If that works, then all you need to do is add a small amplifier board and you can drive a speaker, for instance:


Restart your arduino IDE and open file->examples->avr_sound and pick any of the 3 included samples.

Connect digital pin 8 and digital pin 9 to a resistor ladder then to an earphone. If you want to use a bigger speaker then you need a transistor.
