Functional Description
3.1
Power Supply
The G25A board is supplied with +12V only. The voltage range is +9.5 V up to +15.5 V
(absolute maximum voltage). The voltage is monitored within these limits.
3.2
Processor Core
The following CPU types are available:

Thermal Considerations
The power dissipation of G25A heavily depends on its processor and I/O configuration
and on the workload.
Power dissipation of a G25A equipped with a high-end 45 W processor is up to 72 W (45
W for the high-end processor and 27 W for the rest of the board).
The G25A provides a very high computing power on a small space. For this reason, it is
vital to provide sufficient airflow (1.5 m/s). A suitable heat sink is provided to meet
thermal requirements.

If you use any other heat sink than that supplied by MEN, or no heat sink
at all, warranty on functionality and reliability of the G25A may cease.
