I want to use a speaker along with the 2 Mic Pi Hat. In the past I was using my own solution with a mini amplifier powered by the 5v GPIO and the Pi headphone jack. But the Pi Hat blocks access to all GPIO so I need to use the speaker out on the Pi Hat. There seems to be little information online at all about how to set this up.
- Is extra USB power really needed, or will a small 4ohm speaker work without power?
- Is there any extra config needed to ensure the speaker connection works?
- Most importantly, where the heck can I get speakers with that particular connector? Or, if I want to use my own speaker which JST plug actually is actually used so I can find one? (After a bit of research I find the JST make many, many different connectors)
