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

I wanted something for my classroom audio system, to not fiddle with wires during class. Exactly what I needed for a perfect price. Now I have one at home and at school. The range isn't awesome, if my phone is in my pocket it will start to cut out. But from my laptop, it works great. Sound quality is good! Connects to my devices easily!

This module works fine but here’s what you should know. I wanted to make a Bluetooth speaker that would reproduce the ring tone of a connected iPhone. Since I was unable to get it to do that I posted a question. Several users said it would do what I wanted but here’s what MakerHawk had to say:“Hello, Not supported. This module does not support incoming call reminders. Best regards”

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.

Received units simply work as they should, no bad surprises despite some negative reviews. Pairs with my iPhone in a snap and stays connected, good audio quality for a basement gym, aux input in an old car, etc.

An affordable way to add Bluetooth to your project. Connects automatically once registered on your device.

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!

This little Bluetooth board does its job perfectly. Easy to integrate into a small amp, no problems at all getting it to connect. Very happy with this little board.

These are the best DIY devices I've purchased in years. I've added BT internally to two speaker systems and the results were amazing. I've actually replaced my BT earphones, which no longer work, by putting one of these in my pocket with a small phone charger I got free from the local lottery guy. Works great!! The best thing is that it benefits from all the BT spec upgrades to BT5.0 - works with almost anything!
