I've tried 3 boards and gotten just above a whisper with 40mm 4ohm 3watt bluetooth speakers. One board didn't work at all. I have done extensive research on the remedy and found no reason for this problem. Many argue that an amplifier is not necessary. I question this claim. I wouldn't have this problem if I hadn't spent months developing my product around the board only to figure out what I did. Okay, back to the drawing board. I give two stars for the beautiful blue light.
