Initially the board was shipped with wrong voltage regulators. I received a mail and later a new replacement board.
The board is made really well and all the documentation can be found on github. You should check for the extra parts first. The encoders for example where only available on mouser/digikey/farnell.
This board did the trick. I'm not great at soldering so having the smaller components already assembled was a great help. The one issue to be aware of is a software issue and not hardware related: https://github.com/googlecreativelab/open-nsynth-super/issues/32 Other than that, don't forget to solder the jumpers on the oled.
