is there any chance to modify (software for using the inbuilt port or soldering a new port) the module to play mp3 via USB?
That’d be awesome - so you can use SD or USB.
Maybe a HDD can be connected to the USB-port as well…
I’d like to build this module into a housing suitable to my HiFi-stereo at home.
But I also like to be a little bit more flexible with the storage.
