Is there a expansion board with mobile broadband.
I’ll like to use the speaker as an mobile broadband access point so i can for an example play Spotify and leave it still playing so it maby need to have a small computer inside also.
Maybe some one has a board like that or know a smart way to do this.
Will it have to be battery operated?
Maybe you could use a Raspberry Pi with Volumio or similar for the Spotify and something like a Netgear Nighthawk MR1100 mobile hotspot 4G LTE router for the hotspot?, it can handle 20 clients.
Hi Henrik,
You would need a pi hat DAC module to feed your amplifier for the speakers.
IMHO, the setup you are requiring is probably best done without Arylic boards involved.
