[Community] GTA04A5 ready to be pre-ordered

[Sven Dyroff]

Hello Nikolaus,

thanks for the good news! Meanwhile I decided not to travel to Brussels 
next week, but I think we will meet later this year.

Best regards
   Sven

Hello Nikolaus, 

I'm interested in the GTA04A5, but only when available as complete phone 
with the new case kit. Until then I'm satisfied with my GTA04A4 within its 
GTA02 case... 

Yes, there is good progress. If you can come to FOSDEM we might have 
something to demonstrate.

Not yet the new GTA04A5 case (that needs some fine tuning), but the 7004 
tablet case - but using the same approach.

The "approach" is to generate Python files from the original CAD files for 
the PCB contour and all components.
These Python files can be parsed by FreeCAD and they create e.g. boxes, 
cylinders etc.

Another Python script looks up coordinates of components (e.g. display, 
buttons, holes) and create the shape
of the case so that it exactly fits because it calculates the coordinates.

Finally, everything is saved as STEP or STL and is ready to 3D print.

So we have tested that approach with the 7004 prototype and it can be used 
for all future variants.

BR,
Nikolaus


Best regards 
   Sven

Hi all,
finally, the GTA04A5 batch is ready for production and we are open for 
pre-orders through

                <http://www.handheld-linux.com/wiki.php?page=GTA04>

What will be different to GTA04A4?

* the GPS receiver can provide a 1 second impulse interrupt to the CPU
* the infrared receiver can be independently powered off (it was 
alternatively powered with RS232 before)
* some sensors have been upgraded to non-obsolete versions (e.g. BMA180 is 
out of production)
* WLAN/BT power controlled through a GPIO (so that VAUX4 is now free for 
other use)
* 6-pin ZIF connector for external keyboard or other I2C devices
* it is possible to use a new earpiece (from Knowles) so that we finally 
can offer a complete case kit
* the GPS antenna switch has been redesigned
* improved headset detection hardware
* CPU will be always 1 GHz and Memory 512MB RAM / 1GB NAND
* UMTS module may have newer firmware inside (tbc.)
* there is a plan for a 3D printed case (approx. 50 EUR) with integrated 
touch pen
* there will be 3D data (STEP) of the PCB and components so that you can 
design your own case that fits with a micrometer precision :)

Preliminary (there may still come minor changes coming from PCB
Layout tuning and from first production feedback) schematics can be found
