I'm trying to pick a Bluetooth module to use in a portable speaker. Looking at a few things available on aliexpress.
Bluetooth Stereo Audio Modules Modification Wireless Speaker Amplifier Audio KRC-86B V4.0 DIY Module
Bluetooth Stereo Audio Modules Modification Wireless Speaker Amplifier Audio KRC 86B V4.0 DIY Module-in Other Electronic Components from Electronic Components & Supplies on Aliexpress.com | Alibaba Group
Has anyone used the one linked above?
This one: New XS3868 Bluetooth Stereo Audio Module OVC3860 Supports A2DP AVRCP Good
New XS3868 Bluetooth Stereo Audio Module OVC3860 Supports A2DP AVRCP Good-in Other Electronic Components from Electronic Components & Supplies on Aliexpress.com | Alibaba Group
Shows up often, but it looks like it has differential outputs L+, L-, R+, R-. That would definitely complicate things. I'm using a class d amp with single ended input.
I guess another option would be to get a cheap usb-chargeable Bluetooth receiver in a case with 3.5mm output like this: Universal 3.5mm Car Bluetooth Audio Music Receiver Adapter Auto AUX Streaming A2DP Kit for Speaker Headphone
Universal 3.5mm Car Bluetooth Audio Music Receiver Adapter Auto AUX Streaming A2DP Kit for Speaker Headphone-in Speakers from Consumer Electronics on Aliexpress.com | Alibaba Group
and take it apart for the pcb. Any thoughts?
In case it makes any difference I'm using 7.4v li ion to power the amp and will use 5v ldo to drop the voltage down for the Bluetooth module.
