Moode and Pi Zero W

[Leviathan]

If OP doesn't have enclosure constraints a Pi-3A+ which has 4-core ARM7 CPU, dual-band 2.4 GHz and 5 GHz WiFi and integrated USB port would be a good choice.

Thanks Tim.
I’m not familiar with this model of Pi and had to look up the spec.
with only a single USB port; given that I would want to store FLACs locally and use the USB socket for output to the DAC, presumably the FLAC files need to be stored on the same card as the op sys? Not something I’ve tried before.
