The HiFiBerry Digi+ transformer version is a high-quality S/PDIF output board for the Raspberry Pi (newer models with 40 pin GPIO connector). Additionally to the standard version, it features fully galvanic isolation of the electrical output.
•Dedicated S/PDIF interface chip supports up to 192kHz/24bit resolution
•Optical (Toslink) and electrical outputs
•Full galvanic isolation between the Raspberry Pi and your DAC on the electrical output
•Bit-perfect output, audio data stream will not be modified in any way
•Connects directly to the Raspberry Pi, no additional cables needed
•No soldering, comes as a prefabricated kit. You just plug it onto the Raspberry Pi, it conforms to the Raspberry Pi hardware-attached-on-top (HAT) specification.
•Compatible with Raspberry Pi models A+,B+, 2B and 3B
•Directly powered from the Raspberry Pi, no additional power supply
