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. No, the GTA04A5 will keep the Neo's exterior as it is. It is still a motherboard replacement. But as before you may be able to design your own case around it. 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? Initially we tried with the Telit modems but they were not flat enough and we would have had to sacrifice the speaker (handsfree). Fortunately we found the GTM601 which is used in the GTA04A1-A4. 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 also have Qualcomm inside. 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. The same holds with the Cinterion PxS8 modules. Documentation is also available w/o problems. We are currently evaluating all these options, but there are technical and commercial aspects to consider. E.g. the Telit xE910 modems are 10% thicker and likely still too thick. 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. There is no plan to change the CPU since the OMAP3/DM3730 is still the best mobile processor that can easily be purchased in small quantities. And (despite the GPU) it is very well documented and supported by mainline linux. So please don't expect a wonder to happen... Just small steps and improvements.

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

Yes, it is a Sirf IV chip with 40 channels and higher sensitivity. But I have found no reference that it is possible to increase the sampling rate higher than 1/s. It is only possible to reduce it to 1/30s to save more power. What is your application that you need 5 data points every second? Is it possible to interpolate by using the velocity and direction information?

Re: GTA04A5 ready to be pre-ordered
maybe I have misunderstood then. From your initial response I understood that the gps receiver of the gta04a4 would have a lower sampling frequency than the gps receiver of the gta04a5 due to some hardware wiring and as I you stated in the gta04a5 anouncement the gta04a5 can provide now with the hardware fix a * the GPS receiver can provide a 1 second impulse interrupt to the CPU so my conclusion was that the gta04a4 cannot sample at with 1Hz but must be slower. I haven't had the time to change my gta02 to an gta04 so I could not test the difference myself, but I remember reading the thread [1] it was re- ported that the gta02 gps was capable to sample at much higher rates (4Hz standard, max 20Hz reported). Sampling at 1Hz at 60km/h means an update every ~17m which in most navigation situations should be ok, but if you have complex crossings with more than two alternative lanes then the lag becomes a problem. best regards robin [1] http://comments.gmane.org/gmane.comp.handhelds.openmoko.community/62642 ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
