GTA04A5 ready to be pre-ordered</font>

<br><tt><font size="2">Hi all,<br>
finally, the GTA04A5 batch is ready for production and we are open for
pre-orders through<br>
<br>
<</font></tt><a href="http://www.handheld-linux.com/wiki.php?page=GTA04"><tt><font size="2">http://www.handheld-linux.com/wiki.php?page=GTA04</font></tt></a><tt><font size="2">><br>
<br>
What will be different to GTA04A4?<br>
<br>
* the GPS receiver can provide a 1 second impulse interrupt to the CPU<br>
* the infrared receiver can be independently powered off (it was alternatively
powered with RS232 before)<br>
* some sensors have been upgraded to non-obsolete versions (e.g. BMA180
is out of production)<br>
* WLAN/BT power controlled through a GPIO (so that VAUX4 is now free for
other use)<br>
* 6-pin ZIF connector for external keyboard or other I2C devices<br>
* it is possible to use a new earpiece (from Knowles) so that we finally
can offer a complete case kit<br>
* the GPS antenna switch has been redesigned<br>
* improved headset detection hardware<br>
* CPU will be always 1 GHz and Memory 512MB RAM / 1GB NAND<br>
* UMTS module may have newer firmware inside (tbc.)<br>
* there is a plan for a 3D printed case (approx. 50 EUR) with integrated
touch pen<br>
* 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 :)<br>
<br>
Preliminary (there may still come minor changes coming from PCB<br>
Layout tuning and from first production feedback) schematics can be found
