The board below is exactly the same as the OEM board except for the connectors to the right of the picture.
These are just blank connectors on the OEM board. They were not populated with any sensors or I/O.
You can access some of the GPIO pins of the board with the PMOD (black one at the bottom of the picture) or the Grove connectors to the left of the picture.
This shouldn't impact your use of the board.
