Openmoko Beagle Hybrid

Sun May 23 15:12:00 CEST 2010

Nikolaus,

I agree you should first play with something that is available.

The information I got is from eurocircuit.com,
The price is based on 4 layer 150 * 60 mm; just a wild guess of the size and
layers based on standard technology, but giving an indication.
More about the possibilities can be read in
http://www.eurocircuits.com/images/stories/ec09/ec-services-leaflet-uk-english-4-2010-v2.pdf.
I did not check any guidelines and requirements, so hard to say what suits.
If somebody could provide more detailed information or point in a direction,
a more serious price could be obtained.

Regards,
Martijn

>>
>>        • experimenting with touchscreen and new user interfaces on

>>        • learn how the OMAP3530 CPU works
>>        • make it a truly open mobile application development platform by

>>        • investigate how an Openmoko with UMTS and OMAP3530 feels (not

>>        • porting SHR, QtMoko, Android, etc. to ARM-Cortex A8

>> And here some feature list:

>>        • 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
