Review on DEVMO CT14 Micro 4.2 Stereo Bluetooth Power Amplifier Board Audio Module 5VF 5W+5W with Charging Port - Ideal for DIY Sound Box Speaker Refitting by Anthony Tegan

I bought this for a Bluetooth speaker 3D printing project and it works absolutely as advertised. The included braids were a nice touch. Sound quality is good for such a small board, even through the redesigned PC speakers I used. However, there are some strange features. When you turn on the board, it guides you through the pairing process in extremely broken English at 5000% volume. I'm not kidding about the volume. No matter what I paired with it, I could never get anything else to play, even at half volume it playing pairing instructions. It also features the world's brightest blue LED and constantly flashes to let you know it's still playing, just in case listening to your music isn't enough. I printed the speaker enclosure using 3mm walls and I can see the LED blinking through the plastic. This LED makes serious competition for the midday sun.
