Product description

This Bluetooth audio module enables wireless playback of audio content through speakers or headphones. The receiver connects wirelessly to smartphones, tablets, or other Bluetooth transmitters and outputs the signal without additional wiring.

The 5 V operating voltage allows direct connection to common microcontroller boards such as Arduino or similar systems. The I2C or serial interface allows you to adjust the volume, change tracks, or query the pairing status. The stereo output delivers up to 2*3 W of power, which is sufficient for small to medium-sized speakers or headphones in your project.

Possible applications range from music playback in robotics projects and voice output in smart home prototypes to audio feedback in interactive installations. The integrated battery of the Bluetooth chip requires occasional recharging but buffers brief power interruptions.

Speakers or headphones with a suitable connector are required for operation. The typical range is 10 to 20 meters, depending on obstacles and sources of interference in the surroundings. Connection is made via pin headers or screw terminals, depending on the model variant.

Safety information

The module is intended exclusively for building prototypes and for testing and development purposes and is not suitable for integration into household electrical circuits. Work on or near electrical installations must be carried out by qualified electricians. If you are unsure about the power supply or connection to power supply units, consult a qualified electrician before commissioning.
