5.4 Expansion Module and Device Design and Installation
5.4.1 Physical Space Considerations
Whether installing a non-standard expansion device into an existing Psion Teklogix module (back
cover, end-cap or pod expansion), or creating a custom module to contain an expansion device, it
is vitally important that your device does not intrude on space already occupied by the internal
components of the hand-held computer.
To assist you in this, the following 3D files are included in the HDK:
To assist in forward-compatibility, these files show areas that will be occupied by modules
(such as the WWAN radio), which are unavailable in the Omnii XT10 but which will appear
in future models.
The STEP files also show the exact locations of the expansion ports in three dimensions so that
you can design your device and flex cables to align properly. These locations are also shown in the
following two-dimensional .dwg files:
The information in the above files, in conjunction with the files indicated in the sections
that follow, will allow you to design modules that fit and connect precisely with your Omnii
hand-held computer.
