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.
