Climatic and operational conditions
The operating temperature range strongly depends on the installation situation (heat dissipation by heat conduction and
convection); hence, no fixed value can be given for the whole assembly.
Detailed information regarding the thermal characteristics of the i.MX6 is to be taken from the NXP Data Sheets (1), (2), and (3).
In general, a reliable operation is given when following conditions are met:

With the QuadPlus CPU, a very good thermal connection must be ensured.
