The [schematic](https://download.mikroe.com/documents/add-on-boards/click/3d-hall-4-click/3D_Hall_4_click_v101_Schematic.PDF) for the board would seem to indicate that the featured device is powered from the 5V supply. The Vcc selection determines the supply reference for the digital interface, but not which supply the SENM3Dx device is powered from.
