The Fe-Pi Digital Audio Z V1 is designed to provide a complete low cost audio solution for Raspberry Pi 2, 3, and Zero, needing S/PDIF output.

• Small Raspberry Pi Zero PCB footprint.

• Cirrus Logic WM8804 S/PDIF Digital Interface Transceiver.

• RCA and optical TOSLINK Output jacks.

• 2x20pin 2.54mm female header and 40pin male breakable header included!

Configuring Fe-Pi Digital Audio is done using Device Tree overlays.

To do this, you must edit /boot/config.txt and add the following line... dtoverlay=hifiberry-digi

If you want the on-board Raspberry Pi sound devices(HDMI, 3.5mm jack) to be disabled then change...

dtparam=audio=on to dtparam=audio=off

Run the following command to edit the file.

sudo nano /boot/config.txt
