            The two PCI express slots on the Robotino make it possible to integrate expansion cards
            for individual applications. 
In order to install an expansion card, remove
            the cover from the control unit and insert the card into one of the two slots. Before
            buying expansion cards, check to make sure that adequate installation space is available
            in the control unit on the Robotino. 
If required, an additional power supply
            is available for expansion cards. Connections with 12 and 3.3 V (max. 100 mA), as well
            as an ATX connection, are provided. 
Note: Before removing the cover, the
            seal on the base of the control unit must be opened. When removing the cover, be sure
            not to damage any of the control unit's electronic components or drop any objects onto
            the main PCB.
