Review on 🔊 NoYiTo DC12V PAM8610 Portable Mini Stereo Amplifier Board - 10W x 2 Class D Digital Audio Amplify Module, Dual Channel Amp by April Irvin

I don't do general audio. I wanted to use this to send a specific frequency to a piezo tweeter as part of a sonar experiment. The amp shuts down after an impulse and needs to be cycled on and off, possibly due to some sort of protection circuitry expecting a 4 or 8 ohm load per channel rather than a high impedance tweeter with no crossover. In addition, there is noise at the output even without an input, so that the sound does not appear so quiet. It's a complete failure for me, but I'm giving it three stars because my app is off the beaten path and I assume it can work just fine with regular audio.
