Bill of Material
If a component is not available from a seller, try another seller that offers the same component.

Where to find the components for the webradio on AliExpress:



If you only use the web interface to control the radio you don't need the push buttons.

The PCB uses GPIO 16 for the DCS pin of the VS1053, so set this accordingly in defaultprefs.h:
