Openmoko Beagle Hybrid

[Yocto]

> I haven't seen a discussion about redesign of the board, the design files (schematics in Orcad) are available, so you can downsize the connectors used and fit it in an existing casing.

Could we, also, consider the option of using a "smaller" board like the Gumstix Overo ?

OMAP3503 with ARM Cortex-A8 at 600MHz
256MB RAM / 256MB Flash
[ 17mm x 58mm x 4.2mm ].

  Hi,
  First of all: nice project, could be a nice follow up for the freerunner.

  I have been looking at the discussions a little bit. Main discussion is how to make a new casing that fits around the beagle board, how to produce and what it costs.
  I haven't seen a discussion about redesign of the board, the design files (schematics in Orcad) are available, so you can downsize the connectors used and fit it in an existing casing. I have a price of a PCB (without parts) at low volumes (50 pieces) at less than €15.
  Assembly of low quantitiy boards will be very expensive (make it double the components price), so a DIY project for assembly of the boards will make the PCB fit for a reasonable price.

  Regards,
  Martijn

    There is now a new Wiki page for the project:

           http://wiki.openmoko.org/wiki/Openmoko_Beagle_Hybrid

    I have received some questions why we did not put all this into a nice
    design. The main reason is that we can't redesign the Beagleboard (it
    has fixed dimensions) and we can't afford to build plastic injection
    moulds (if someone has an idea how to reduce cost this is very
    welcome). So the easiest solution was to combine what we have: a given
    Beagleboard and the Freerunner case.

    Other questions were what one could do with this. Here some ideas (not
    assuming it is complete - you may have more and it is a platform for
    your creativity):

           • experimenting with touchscreen and new user interfaces on Beagleboard
           • learn how the OMAP3530 CPU works
           • make it a truly open mobile application development platform by
    adding a battery pack and a UMTS usb stick
           • investigate how an Openmoko with UMTS and OMAP3530 feels (not from
    haptics but screen operation and UMTS speed)
           • porting SHR, QtMoko, Android, etc. to ARM-Cortex A8

    And here some feature list:

           • PCB that fits into Freerunner case (top cover and middle part after
    cutting a hole)
           • works also without such a case (except speakers and earset)
           • Toppoly LCM interface (same display as used in the Freerunner -
    otherwise it would not fit into the case)
           • TSC2007 touch screen controller
           • Microphone
           • Earset and Speaker connector (for those sitting in the Freerunner
    case)
           • 2 buttons (AUX and Power)
           • 2 dual color LEDs (in the AUX and Power buttons)
           • vibracall driver
           • headset jack to connect microphone, earset and speaker

    For the software, we have to rearrange the code on our server a little
    and then it will be made public.

    Finally, here you can do preorders:
