5pcs Bluetooth Audio Receiver Board BT 5.0 Stereo Audio Amplifier 3.7-5V Car Speaker Amplifier for DIY

These little things are great! The speed and reliability of the things far exceeded my expectations. Connects instantly, easily identifiable markings on these things. Easily can control the volume with my phone and don’t seem to heat up under normal load. LED indicator is way brighter than it needs to be but not at all a dealbreaker. Very happy with the purchase thus far!

I love this PCB. It has a great connection with excellent sound quality. Instead of buying a megabuck sound bar I bought this Bluetooth PCB and used a computer sound system. It sounds GREAT.

The MakerHawk 2pcs Bluetooth Audio board works fine. There is no human voice for power, connection, etc, only beeps. Wish there was an easy way to natively rename it.

I was hoping for a data sheet listing specks and application notes, but this CCA does it easily and very well. Connects to just about any phone or other Bluetooth device and the sound quality is great.

I am using this module in my car which has no bluetooth. I stream music from my phone to car audio. Good quality audio and no noise. Recommend for DIY bluetooth receiver projects if you have micro USB, 3.5mm cables, power source. This is receiver only module. This is a bluetooth transmitter. Pros: Amplifies audio Small and compact Good quality No noise Good product for the price Cons: Not 2-in-1 transmitter and receiver. Not Type C usb power input No protective case No inbuilt rechargeable battery Cables not supplied

These modules are amazing and exceed my expectations. My wife and I like to listen to audiobooks on long drives. We use over the ears headphones for the best sound and I tried to use audio splitter from my phone. the phone was no capable of outputting sufficient power for both headphones. I ordered these modules so that I can bluetooth the sound to the module and use the headphones. It worked incredibly well. The volume is excellent in both sets as if the module has an amp built in. I am powering the module from a rechargeable battery and they work perfectly. I will use the second module to build a wireless speaker. There are two points I have to mention. The first is the badly pronounced tones when the module turns on and off. and the second is that the modules are very bass heavy. These two points did not detract from my experience but is something to be aware of.

These are great little modules, at least for the price. Sound is pretty good and BT connection is easy. They have added some convenient pads for power and audio output signals. However, I can't get it to function as a sound card. I have connected the two sets of tinned pads on the back side which allow the USB D+ and D- signals to reach the chip, but plugging into a PC does not enumerate or even recognize anything has been connected to the USB port. There seems to be a complete lack of information on how to use this as a sound card except for 'When the computer sound card is used: tin the pads in the two boxes corresponding to the Sound Card on the back of the module, and connect it to the computer USB port through the USB cable at this time, and it can be used as a sound card.' Perhaps there is a way this will work as a sound card, but so far I've tried 3 of them and am having no luck. Great product otherwise!

Got power from cig lighter to USB plug and plugged in the phone. My no jack POS phone now plays music and reads book to me. Reordered for gifts to friends with POS phones.

Very good product as is described by the seller.

Works well, sound is good. Connects to only one device at a time. Passive speaker sound is not that great (depends on the resistance range). Works with old mobile charger (5v). overall very nice.
