Specific 3D Mechanical Models
The OSM iMX91 3D model is simplified and contains only the PCB and the CPU. It is intended to be used for heat spreader or heat sink designs. The CPU height is a typical value. Due to production tolerances, the actual height of the assembled component can be different. Please use the OSM iMX91 Family Specification with the maximum component height for testing the mechanical fit. This ensures the mechanical design fits all current OSM iMX91 modules as well as future releases.

Product Number (PID8) Format
The format of the 8-digits Product Number (PID8) is the following:
The below table describes the structure of the Product Number (PID8):
| Field | Description |
|---|---|
| PPPP | 4-digits number, indicating the Product Configuration (PID4) that describes the key properties of the product (e.g. Product Group, RAM capacity, etc.) |
| VV | 2-digits number, indicating the Major and Minor Version (in that order) |
| AA | 2-digits number, indicating the Assembly Variant |
See the complete list of available combinations on the Revision History table of the corresponding product page.
Example
Product number (PID8): 00291100:
0029: Apalis iMX6D 512MB
11: Major Version 1, Minor Version 1, Version V1.1 in short
00: Assembly Variant A
