superb product

Grande plage d'utilisation de l'alimentation

I had an old ipod dock/speaker with no Bluetooth capability. It was pretty quick and easy to find a DC power line within that and hook this up. The wide voltage compatibility makes this much easier. The dock had an aux in so the audio connection was similarly easy. The only wrinkle in my plan was that the dock was supplying power continuously to the board so it grabbed my phone's Bluetooth connection wherever was nearby. I did not get a chance to listen critically to it since this was a pretty average speaker. And then that speaker died (of unrelated causes). But I like the ease of use, the thoughtful (e.g. different connection options for audio out) and quality build. I plan to use it again with an older NAD amp or possibly on a friend's old, non-Bluetooth car stereo. Low price makes it particularly easy to recommend.

Ich habe dieses Bluetooth-Modul in ein aktives Lautsprechersystem integriert. Das Modul funktioniert zuverlässig und lässt sich problemlos mit einer stabilisierten 12 V-Versorgung betreiben. Die Audioqualität ist sauber, ohne hörbare Verzerrungen, und die Bluetooth-Verbindung ist schnell sowie stabil (getestet auf ca. 8–10 m Reichweite in Innenräumen). Ich habe zur Verbesserung der Stromversorgung zusätzliche Kondensatoren (100 nF + 1000 µF) direkt an den Versorgungspins hinzugefügt und an den Audioausgängen ein kleines RC-Filter angebracht, um Reststörungen zu eliminieren. Nach diesen Anpassungen arbeitet das Modul absolut rauschfrei. Vorteile: Breiter Versorgungsspannungsbereich (5–35 V) Gute Audioqualität und stabiles Signal Kompakte Bauform, einfach zu integrieren Schnelle Bluetooth-Kopplung Nachteile: Werkseitig kaum Filterung auf der Versorgungsspannung, kann bei „lauten“ Netzteilen hörbares Rauschen erzeugen Status-LED ist relativ hell Fazit: Sehr gutes Modul für DIY-Projekte oder zur Nachrüstung älterer Verstärker und Aktivboxen. Mit minimaler zusätzlicher Entstörung auf der Spannungsversorgung liefert es eine hervorragende Leistung.

Surprisingly capable little module for the price. Setup was quick and painless — it paired instantly and delivered a clean, stable Bluetooth signal without the usual background hiss or random dropouts you get with cheaper boards. The sound quality is more than decent, with good dynamics and clarity once connected to a proper amp. It’s small, easy to integrate into any DIY audio project, and works exactly as advertised. Feels like a budget hack for anyone who wants to add wireless streaming to an existing system without spending much. A no-nonsense, great-value Bluetooth receiver that simply gets the job done.

Prodotto molto valido. Ampio range di alimentazione, ottimo segnale audio: potente e pulito. L'ho utilizzato per dotare l'ics della mia lancia Lybra di bluetooth, lo uso da una settimana circa e devo dire che funziona perfettamente. Pairing rapidissimo e non si avverte alcun disturbo da interferenza. Ottimo per gli appassionati di fai da te. Molto soddisfatto, ottimo rapporto qualità prezzo,ne comprerò sicuramente un'altro.
