Overview

This chapter describes the physical aspects of manufacturing and mounting peripherals to the base of

the EP10.

4.2

Materials

The EP10 snap-modules manufactured by Psion are manufactured using ABS + PC CX7240, and the textur-

ing is VDI27. We recommend using a similar material for your peripherals.

HDK Mechanical Files

The Hardware Development Kit provides the following mechanical models and drawings:

4.3.1

3D Files

STEP files provide 3D models of the EP10 and snap modules for viewing with CAD software. These models

give the exact forms and dimensions of the components so that peripherals can be designed to fit the

EP10 precisely.

2D Files

PDF files provide 2D drawings of the surfaces and attachment points of the EP10 and snap modules. The

drawings show the exact locations and relative positions of screw mountings, etc.

Peripheral Design

4.4.1

Physical Design Considerations

Custom EP10 peripherals connect through the docking connector on the base of the unit. Whether this pe-

ripheral uses a "snap module"-type design that attaches to the unit and travels with it, or a "desktop

dock"-type design, in which the EP10 will remain at rest, there are a few important points to bear in mind

when designing your peripheral.

There are no threaded inserts for screws in the EP10 to secure the peripheral. However, there is a small

cavity on both sides of the EP10 for spring-mounted catches to latch on to. Your peripheral should include
