APT-X Bluetooth Audio Receiver HW Module Review
Review of a Bluetooth module sold frequently on eBay.
It turns out the module has a serious flaw and creates heavy distortion when the received Bluetooth signal is strong.
Here is a fix that will make it work well as a Bluetooth module but unfortunately the AUX in will be disconnected:
1. remove C2, C15, C23, C25
2. connect the free right solder pad below C15 to the top solder pad of C25
3. connect the free right solder pad above C2 to the top solder pad of C23
This connects the driver outputs directly to the 3.5mm output connector.
