    Ready-to-use module and very easy to implement. Very low-noise if implemented correctly. Wondering if it’s possible to disable the built-in sound effects (when powered on it plays a short jingle, and when pairing too).

    Good module, works as expected. The solder tabs can be a little fragile, so be careful when soldering.
