I was trying to get this mixtape to work for my wife.
I’ve just soldered my Speaker pHAT the other day and today I tried it to play some audio. But I noticed when I switched the Raspberry Pi Zero with Speaker pHAT off, the speaker or at least the magnet is burning hot. And also the pHAT smells a bit like burning plastic.
So now I’m afraid I might have burned the speaker. Or should a heat sink on the pi suffice to fix this?
I’m no soldering ninja, so maybe I’ve also shorted the circuit somewhere.
Hope someone can help me out.
