WIFI DAC - Raspberry Pi Zero W Music Player

A small cheap music player based on a "Raspberry Pi Zero W" and a cheap USB soundcard.

I use it to play Spotify or via Bluetooth with the software from www.moodeaudio.org 

To connect the USB soundcard to the Raspberry I use a very small OTG USB adapter, see picture above.

The USB cable supplying power to the other USB micro connector on the Raspberry Pi Zero needs to have a quite small USB plug since the USB soundcard is slightly in the way. I trimmed down the connector with a pair of pliers to make it fit. A 90 degree angle plug could maybe work too.
