hi..
i know there is DIGI+ https://www.hifiberry.com/digiplus/
expansion card for the pi..and it just bitstreams data.
Then i found this : http://www.amazon.com/Kuman-SC07-Raspbe ... 6PYDMHV9NV
and want to ask if it is not exaclty the same board ?
Because on all pages they say its a wolfson sound card.. but in my opieion this has nothing to do with a soundcard..so is this a soundcard or its just expansion card to bitstream to an external dac.
