I hope this is the right section.
I have a problem that seems complex to me but maybe it is not.
I just assembled a smart car kit with the pi3 b+ that occupy some of the gpio connectors (the 3v one and other three).
I already planned to add an usb microphone, it has a camera and an ultrasonic sensor and now I would like to add a speaker.
Unfortunately all the hats (like phat) needs all of the gpios.
I planned to buy A 3.5mm speaker but it would need too much space and I don't think it would be very powerful. Are there any usb micro speakers or speaker modules which needs only some gpios and don't need an amp?
