  • Simple solder pads or plug-in headers make integration straightforward for hobbyists.

Upgrade your audio setup with a reliable Bluetooth module.

FAQs

Most modules operate on 3.3 V to 5 V DC; check the datasheet before connecting.

Yes, many modules provide line-level output that connects to AUX inputs on head units.

Some models include a mic pin for hands-free calls; others are audio-output only.

Expect 10 meters in open space; walls and interference may reduce distance.

Certain modules allow updates via USB or UART; consult the manufacturer for tools.
