4 Mechanical and Thermal Consideration
4.1 Module Connector
The Colibri modules fit into a regular 2.5V (DDR1) SO-DIMM200 memory socket. Please note there
are two versions of the 200-pin SO-DIMM connector available. The Colibri module is only
compatible with the variant that is designed for DDR1 modules with 2.5V. The 1.8V DDR2 variant
has a different notch position and is therefore not compatible.
There are many suitable connectors from different manufacturers available in different stacking
heights. A selection of SO-DIMM200 socket manufacturers is listed below:

4.2 Fixation of the Module
The SO-DIMM connector features a locking mechanism that is reliable for many applications.
Additional fixation might be required to ensure the proper connection of the module at high
vibration or shock situations. The Colibri module offers different solutions for the fixation.
Figure 57: Colibri Fastener
Toradex offers Colibri Fastener for an easy-to-install fixation. Two fasteners are required for
holding the module. The fastener supports a SO-DIMM connector height of 5.2mm only. If a
connector with a different height is used, another fixation solution is required. Please note,
inserting the Colibri module is critical. If done wrong, the Colibri can be damaged due to
mechanical stress! More information, including a module inserting guide, can be found here:
