   * SATA
   * MIPI Camera
   * Parallel Camera
   * Power button for suspend,resume and power off
   * Mini PCI Express (**)
   * Bluetooth
 
 (**) Interface is supported as long as kernel includes the PCI Express 
      final device driver. 
 
4.- Limitations:
   * Most of the Digi Android Sample Applications will not work with the 
     Android emulator as required physic interfaces and APIs are not 
	 available in virtual mode.
   * In order to work with Android physic devices in Linux, ADB daemon 
     must be started with root permissions. Otherwise, connected Android
	 physic devices will appear with ??????????? as serial number and no
	 actions will be available against this device.
   * Environment may hang when a network device is disconnected and 
     connected after a debug session
   * The micro SD card slot doesn't support CD. To make the SD card 
     available to the system the card need to inserted before booting the
     device.
   * The CANListener has a limit of 5 CAN IDs that it can filter. If more than 5 IDs is used
     no CAN message will be received. (ADK4A-84)
   * When using the parallel camera the picture size in the camera application settings
     should be changed to VGA. Because the maximum resolution of the camera driver is set to
     640x480.
   * HDMI audio is only supported when using supported CEA-861-E video modes. When using
     non CEA video modes the HDMI audio clock will not be correctly setup and the HDMI audio
     cannot be used. This is a limitation of the i.MX6 integrated HDMI transmitter.

5.- Known Issues:
   * In Linux machines Java must be installed in order to run the 
     Android SDK Manager.
   * In order to build the Android sources, Java JDK version 1.6.0_45 or 
     higher is recommended. It has been observed that with previous Java 
     versions the Android build system might be failing.
   * If enabling Wifi hotspot functionality a maximum of 5 devices can be 
     connected.
   * It has been observed that the system might to not boot correctly. A
     workaround has been added to reboot the system in that case.
   * It has been observed that with the combination LVDS + MIPI camera, the
     camera will fail to resume from suspend on the ConnectCore6 SBC.
