  • Page 30: Reference Design

    User manual Oceanus-I 6 Reference design Oceanus-I was tested and certified on the corresponding Oceanus-I EV-Board. For the com- pliance with the EU directive 2014/53/EU Annex I, the EV-Board serves as reference design. This is no discrepancy due to the fact that the EV-Board itself does not fall within the scope of the EU directive 2014/53/EU Annex I as the module is tested on the EV-Board, which is also the recommended use.
