Any galvanic isolation of the electrical SPDIF out?

Former Member

An impressive little board with great flexibility at this price point. Does anyone know if it has galvanic isolation of the electrical SPDIF out?

  • Looking at the circuit diagram, NO.

     

    Galvanic isolation will be provided with an optical connection. AFAIK you can get coax to optical SPDIF

    converters reasonably cheaply online. If you are feeling adventurous, there is info available online to make

    your own.

     

    If you are worried about earth/ground loops, you could operate you raspi system from a double insulated power

    supply that only has a 2 wire power lead or unearthed mains connection. If the power supply you are using has

    an earth/ground connection or a 3 wire power lead, DO NOT disconnect the earth/ground connection - you may

    make the power supply or connected equipment dangerous to use.

    Thank you for looking this up. It did look like it didn't have it on the board. I was planning on using this as a transport for hifi audio, but going via optical is not an option. I might still get it for another purpose, because it is highly versatile.
