Review on 🔊 HiLetgo 3pcs M28 Wireless Bluetooth MP3 Audio Receiver Board BLT 4.2 - Lossless Decoder & Stereo Sound Module with Bluetooth 4.2 Connectivity by Manuel Gfx

These little boards are great. Really good sound quality and my setup doesn't require a ground loop breaker between it and the amp. Fantastic value for money. Soldering can be a little tricky if your skills aren't very good (mine are significantly worse). However, this is possible with a little care. I used one of these to make a bluetooth speaker in a small package. I used a small board that allows you to power the bluetooth board with 5v and the amplifier board with 12v. pleasure works.
