The board can be powered using the 5V power from host 3D printer controller and is connected using the supplied 2-wire async serial interface cable. Configuration and use is very easy thanks to the user-friendly ReprapFirmware interface. Connections to the external SD card socket that is included on most compatible displays is available via a 10-way ribbon cable connector on version 2.0 PanelDue boards.
