XY-WRBT 5.0 Bluetooth Decoder Board - Lossless Decoder, Stereo Audio Module, Wide Voltage Receiver

Very easy to add to existing system. I have an older RV and the BT was very limited in distance. This product using BT 5.0 extended the distance by 3 times what I had. I wanted to be able to control my music without being right next to the camper. Easy to wire directly into back of the existing system, worked with 12V as the existing system. Very satisfied.

Picture shows a pair, meaning 2 of the product. BUT delivered on 1. Misleading !!!

I had relatively no issues working with this. Connect a power source, connect outputs and you are good to go. I did have one minor issue with my USB battery not liking the board- in the sense it would shut off after 5 seconds thinking nothing was actually attached. This was a testing problem and not what I'd call a real world problem though.

This is a super cool, super simple little board. You power it up, either by a 5V micro-USB port, or solder a power connection to the 3.7V-24V terminal. Connect it to your Bluetooth (it shows up as XY-WRBT), and get the audio out on a 3.5mm jack. It has a simple left/right/middle multi-function switch that does the standard Bluetooth audio functions (play, pause, skip, etc.). If you build any sort of audio project, this is a very simple way to add Bluetooth to it for under $10. I tested it with just the USB power and headphones, and verified all functionality. The audio quality itself is not top-tier audiophile quality (Bluetooth never is anyway), but it’s perfectly acceptable. As far as I can tell it uses the Zhuhai Jieli Technology AC6955F4 chip, which is a pretty capable Bluetooth 5.1 chip. A cool little board. 5 stars!
