Review on MakerHawk Bluetooth Audio Receiver Board – BT 🔊 5.0 Stereo Amplifier for DIY with Car Speaker Support (2pcs) by Tracy Fleurosier

I bought this product for a vintage stereo that I never thought I could turn on Bluetooth. Wonderful! Installed in two minutes. And I'm not a techie. Amazing it works amazing one thing is you have the volume on your phone then adjust the volume with your stereo and I couldn't be happier. I will order two more if my friends hear about this and want one. I mean I'm really amazed. I used double sided tape to stick it to the back of the stereo, plugged it into an outlet and it automatically turns on with the stereo. Make sure you use at least a 5V adapter. Very important!
