RN-52 Breakout board

Hi

I am having problems with this board. I have it hooked up in basic mode playing music from my iPhone. My problem is that between tracks i’m getting a loud buzz from the speakers. Looked for answers but cant find any info on this. help please

How are you powering the module? Are you using external amplified speakers? You are probably getting power supply noise coupled to the inputs or even the outputs of the module’s on-board amplifier. This module needs a very good quality power supply, and all connections to the module should be as short as possible.
