STX Terminology – STX Module
 
The STX Module is a general-purpose processing module containing the complete functionality of the common industrial PC on a very small space.

STX Module

Although equipped with various memory configurations or computational power, STX Module always provides all the functionality through its STX Interface.

STX Module Type

In case that STX Baseboard is to contain some components below the STX Module, it might be necessary to make sure that there is sufficient empty space below the STX Module.

This Hardware Specification defines two types of the STX Modules:

  • Type I. STX Module
  • Type II. STX Module
Type I. STX Module uses 4.6 mm height plugs – it allows minimal high, but it may preclude to use any components on the STX Baseboard underneath the STX Module.

Type I. STX Module heights

Type II. STX Module uses 6.6 mm height plugs – it allows to use the components on the STX Baseboard underneath the STX Module.

Type II. STX Module heights

For detailed description of dimensions and used plugs see Mechanical Specification.

STX Module Style

For various purposes, this Hardware Specification defines two styles of the STX Modules:
  • Bare STX Module
  • Boxed STX Module
Bare STX Module is only a PCB with assembled components and no cooling mechanism implemented. The Bare STX Module is targeted for high integrated embedded and industrial applications where variability is the primary goal. It is presumed that the system designer will provide necessary heat removal according to application requirements.

Bare STX Module

Boxed STX Module has the top cover with heatsink. There is no need for additional heat removal as the heat removal capabilities of the Boxed STX Module are satisfied. Boxed STX Module is an ultimate, easy-to-upgrade solution and have to be designed to comply with mechanical specification.

Boxed STX Module

Side and View Definitions

Bottom side of the STX Module is defined as the side equipped with the STX Interface plugs.
Top side is the opposite side.

Top view for the STX Module is defined as view at the top side.
In opposite, bottom view is defined as view at the bottom side.
