HiFiBerry Digi+ Transformer Version

HiFiBerry Digi+ is a high-quality S/PDIF output for the Raspberry Pi. It uses the I2S sound port that connects directly to the CPU without the need for an additional USB conversion. It supports sample rates up to 192kHz/24bit. It is compatible with Raspberry Pi A+, B+, 2, 3, and ZERO

This  version features an optical output and an transformer-isolated electrical output. The output transformer is shielded, make sure the DAC that you connect to is grounded.

To complete the build you can also purchase a black or a transparent acrylic case to house your Digi+ to help bundle your projects.
