Graphical mapping interface embodiments and method are provided for creating and displaying a schema map, which may be used by a data transformation system to perform a data transformation between at least one source schema and at least one target schema. This provides a \u201ccurrent consumption cap\u201d that fixes an upper limit of current consumption for the NVM, thereby eliminating peak power events. The board has an electrically insulating core layer, with the first and second conductor levels extending on the same of the two faces of the core layer and with the second radio-frequency line at a greater distance from the core layer than the first radio-frequency line. The inserter module may include an energy store and an activation mechanism.
