Review on 🔊 Huazhu DC12V-24V 2.1 Channel TPA3116 Subwoofer Amplifier Board High Power Bluetooth Audio Amplifier Board 50W+50W+100W (Bluetooth Amp) by Heather Peacock

Excellent amplifier. This is my 4th amp of this design and 2nd from this seller. There are several similar ones from different sellers, all the same. This one doesn't have a white USB cable connector, although it does appear in the picture. It seems to be common to all sellers of this amp. I usually just solder the connector and that's it. The second board I ordered from this seller had the USB input holes soldered. I had to use some solder to remove the solder and was able to add the connector easily. I didn't add the USB to the first amp of the project so I don't know if it was soldered or not as it's gone. The first one I ordered from this seller works great as a college dorm amp. I haven't built a speaker system for that yet. I may update this when I do a final build with a power supply/multiswitch etc.
