Hello,
Sorry I found only GTA04A4 but not GTA04A5 with LTE for pre order and
price.
Why
If you look at the date (22 janvier 2013), a long time has passed. We did
start for preorders
back then, but there wasn't enough response. So it was put on hold some
weeks later.
In the meantime the list cited below is still almost correct, but not
everything.
Now, we are *thinking* about restarting the project with *maybe* LTE
(option).
Hi Nikolaus,
glad to hear that, I'd be really happy to see a new device that might
leave the exterior of the Neo's behind for something better.
A long time ago, people were interested in replacing the Calypso with
a Telit modem for future devices; as you might think about a new
platform, I wonder if the Telit modems might be considered, still?
The big difference to the Qualcomms is, that the user documentation is
much better, including a freely available full AT command reference
[2] and more. They have, for example, the new L910 [1] with LTE
support, and as they aren't used by most major phone makers, I'd
assume that they might be more reasonable in delivering smaller,
reasonably priced, batches.
It also includes GNSS (GPS, GLONASS) support (with documented AT
interface), and has VoLTE support (voice over LTE), which makes it
reasonably future-proof.
With an 28.2 * 28.2 * 2.2 mm (LGA 144) package it isn't exactly tiny,
but not that much larger than alternatives I think.
Their modules are all pin-compatible, so the NA and EU variants, as
well as 2G, 3G, 4G variants can be replaced without further changes.
An extra wish would be using a main SoC with ARM Mali graphics, so
free GPU drivers would be realistic (in contrast to all other options
it seems).
I'd certainly be in.

Restarting means to think about all details - and decide if it is now a
better time to
do it. You know world economy has changed, attitudes for openness, freerom
have
changed and people are no longer following that much the top 2 brands.
I.e. please wait for a new announcement.
BR,
Nikolaus
Thanks for your answer
Best regards

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
