The ZK amplifier board functions nicely—Bluetooth pairs quickly and sound is good. The instruction manual is a bit brief, but I managed to figure everything out with a little trial.

The CA-MT21 amplifier board is amazing. Bluetooth 5.0 connects in seconds, the bass is deep, and it handles 24V power without any heat issues. Perfect for my DIY speaker system.
