Bluetooth receiver board

[Laurent]

I was looking to upgrade my Bluetooth receiver, my old one only supported aptX and was over a decade old. Streaming via moOde and Ubuntu worked but wasn't as stable as I wanted.
I found these small QCC5125 and QCC3084 breakout boards on AliExpress for about the price of a cheap lunch.
These are basically the latest Qualcomm bluetooth audio chips, supporting the newest codecs.

The plan was simple: connect it to my RME ADI-2 via S/PDIF coaxial and replace the old PCB in the donor enclosure. The board has clearly labelled pads — VCC, GND, and P20 for S/PDIF output. I replaced the original barrel connector with a USB-C charging board for power, connected P20 to the existing coaxial S/PDIF output socket, and that was essentially it.
After powering up, my Xiaomi 12 immediately found the device and automatically negotiated aptX Adaptive. Switching to LDAC gave me 96kHz/32bits. Connection stability is noticeably better than any software-based solution I've tried.
For the price of a sandwich you get a Qualcomm QCC3084 with LDAC, aptX Adaptive, aptX HD, and rock solid S/PDIF coaxial output. Highly recommended for anyone wanting a clean digital wireless source for a DAC.

I only use wireless when absolutely no other option exists.

An BT only for my kids' phones input or output to their earphones.

Or maybe outdoors like at the beach or a picnic.

Sometimes it is convenient to use wireless, a good implementation should work just fine and not cause too much signal degradation. But if you never use it, then this post probably isn't for you
