Reviewed in the United States on March 10, 2025
I am a purchasing consumer reviewing a product I purchased. I am not receiving anything for posting this.5-stars easy. No complaints, I bought twoSome of the reviews below state this board is a 24-35V device. I don't know about that . It uses a GH27G / AZ1117E power input chip, that's only designed for 13V max. The product description I would say is correct at 12V. I personally only power mine with a standard 5V micro USB cable. I haven't tried it at higher voltages.[3/13/25]Power with a micro-USB plug. Plug into my Larocco PPA headphone amp with a cheap RCA "Y" cable. Thorough listening using my ipad as BT source. Absolutely no issues what so ever after 3 nights of critical listening. The circuit is "black background" silent. No hiss, no hum, no clicks/pops or digital artifact noises of any kind regardless of ipad volume setting. No radio frequency noise / interference either. Sound quality seems to be well balanced no offending boost or cut to the sonic spectrum. It is a very "dry / uncolored" sounding circuit when used as a line level device. I A/B compared it with a plain "Y" cable out of my ipad... and I really could not hear any significant sonic differences. These impressions were made using sennheiser HD650, Koss KSC75, Grado HF-1, Truthear Zero Red, JBL T110. Frankly I am pleasantly surprised. BT connectivity / reliability has been solid... as reliable as the cheap RCA-Y cable it replaces.I bought two of these so I could use my headphone amps with BT. This will help reduce some of the wires and clutter on my desk and nightstand. I will probably mount one in a small project box and just use a micro-USB plug for power. The second one I think I can squeeze in the second amps enclosure, and tap into the 12V DC part of the circuit.The blue LED is CRAZY bright at night. I cover it with a small piece of black electrical tape and it helps. I wish it were the opposite, solid ON when connected to BT and flashing when waiting to be paired. But that's not nearly major enough to take away a star.Reliability of course remains to be seen.I will post dated updates to this review as my opinions change.

For the low price it's pretty nice, puts out surprisingly clean sound and has decent range with the built in antenna with no connection issues. I velcroed it to the bottom of a little plastic box, runs fine off a switching phone charger but seems to sound a little better powered with a transformer based 9 volt wall wort I went with. Theres a little white thing on the board that runs a little warm, an op amp I'm guessing. The only thing I don't like is before it's paired the output is wide open and you get hum out of it. Other than that annoyance it's a great little board.

I have been through like 6 of these. All from various different Ali sellers or bay purchases.This is by far and away the BEST module of the bunch. No, it's not $5.88 ; no it doesn't come with an enclosure, a power supply or a back rub.What it DOES come with ? A well made PCB that's thick and coated. properly and firmly secured SMD components, headers and jumper cables for your project.EXCELLENT quality all around.One word of note for some of you. If you're supplying power to this device from the project you're putting out audio INTO, you're likely going to have some level of Ground Loop noise. It's just the way it is.Your best option for in the car use cases is to isolate it from Radio power either with a DC-DC isolator or provide it battery power. I haven't tested current draw on this but I can't imagine it's more than a few dozen mA.If you're using this integrated into another device, you probably will find it much easier to isolate it. In the car, everything is shared ground so your options are more limited.The other thing you need to be aware of is that the power jack on this is probably fine for prototyping but I would probably want to upgrade it to a screw terminal or direct solder a power qd jumper to it if you plan to mount it semi-permanently into an enclosure etc. I feel like enough vibration or a single shock to the box would knock the power wires out.It's not very 'bitey' and even using dupont cable male probes, they didn't wanna stay in the port. It's just the nature of these very small components. It's probably intended for like 26g wire.

I love this board. It works just as good as it looks. Switches between auxiliary and Bluetooth audio beautifully.PROS: - Affordable - Easy to operate - Comes with cable connectors and extra headers - Built-in audio jacks - Power flexibility through USB or direct power (5v-12V)CONS: - (none)

Usé éste módulo para actualizar un amplificador Sony TA-A50 al hacer la interfase a una entrada que originalmente es destinada para un sintonizador de radio. Naturalmente la instalación requiere de soldadura y un vistazo al manual con los diagramas eléctricos para saber el lugar para instalar la conexión.Suena bien, cumple su función. Me agrada que el módulo tenga provisión para antena externa, pues instalar una ayudará a incrementar el rango de operación.Ampliamente recomendado.

Short and simple:Small, runs on almost any common DC voltage (5V-35V), great sound quality, little power draw, connects quickly and seamlessly. Great for almost any DIY bluetooth project, this is the one to buy.The long story:Used this in a project I just finished, a late 1980s Panasonic RX-FM16 boombox. Instead of D cells the boombox is now powered by an Anker USB battery pack through a USB to 9V adapter. I connected the module also off the 9V line and put it on a switch so it could be turned off when the radio is being used on FM/AM bands. Through some research I was able to figure out which IC on the radio's mainboard was the tape-preamp and remove it, then wire the output from this module (through a 3.5mm male cable) to the pre-amp output pins. Simply push the play button on the tape deck (which now has the motor disconnected and removed) and the amplifier turns on, then switch on the bluetooth module on and you have your music in crystal clear sound. As you can also see everything tucks neatly away in the original battery compartment, as if it was meant to be. Don't mind the hot glue. I've had zero issues with connectivity and the sound quality is excellent, no issues running on 9V but your mileage may vary. Unit connects immediately.
