Hi everybody
I have been searching for days for a proper board for a 3D printed Bluetooth boombox. The problem is I would need it to run on USB rechargable 5 volt battery to avoid having to use a dedicated charger. This cuts down the choices quite devastatingly. Both kinds of modules with or without the Bluetooth are interesting, but surely built-in BT would be great.
I have only found stuff like this:
NS4871 amplifier board 5V 3W amplifier board computer amplifier board 5 volt amplifier board than SP2038-in Integrated Circuits from Electronic Components & Supplies on Aliexpress.com | Alibaba Group
Surely it looks super flimsy, and I would love to find something sturdier with the same voltage.
If you have something in your mind that would be a good choise please let me know.

PAM8403 boards can be found for $1/pc on Ebay. Be sure to get some pinheaders with it, much easier to solder that way.
eBay has USB BT sticks for ~5$, I can recommend them from my experience.

Thanks. I already ordered a couple of PAMs to try out if they would be sufficient. I still search for more convincing modules though. The chances to find one look bad so far.
