Hypercube GND Shield and FPC Bus Board

• The purpose of this board is to provide GND shield PCBs that can be connected to empty positions in a Hypercube.
• The GND shield reduced RF noise propagating from the Hypercube boards into other Hypercubes and their boards.
• A screw terminal near the conduit hole allows the GND wire to be propagated through the conduit holes and terminated. The inside surface is the GND plane. The outside surface is grounded, but as its not 100% needed, 3 sets of FPC bus footprints have been added. It is not necessary to fit any connectors to the FPC positions. Fit FPC connectors if need to use the GND shield board with dual purpose as an FPC bus board.
