Used this board to build a Bluetooth speaker out of 4 inch pvc pipe. Powered it with a 5s 18650 battery pack. This board connects fast to Bluetooth and sounds great on the 4ohm 3.5 inch 30 watt rms speakers and tweeters I used. I will definitely use this again in future builds. The only issue is you have to make connections to the push buttons on the board so you can control the volume and other functions. See the 3 red push buttons in the picture.

Looks well made, connected to my phone with no problems. Plenty loud enough. One component damaged but device still working. My only concern is the range, I can barely get across the room without the signal starting to break up. Looking at the PCB I can see that there is a ground plane under the antenna track. Now all guide lines I have seen state that this area must be kept clear of all tracks. This is a design fault. So I'm not surprised about the range. This could be resolved by replacing the PCB track antenna with a short 1/4 wavelength piece of wire.
