=== Power consumption ===
 
−
Providing theoretical maximum power consumption value would be useless for the majority of system designers building their application upon DWM module.
 
−
Practically speaking, these figures would be of no help when it comes to size power supply unit or to perform thermal design of real systems.
 
−
 
−
Instead, several configurations have been tested in order to provide figures that are measured on real-world use cases.
 
−
 
−
Please note that DWM platform is so flexible that it is virtually impossible to test for all possible configurations and applications on the market.
 
−
The use cases here presented should cover most of real-world scenarios.
 
−
However actual customer's application might require more power than values reported here or customer's use case may be differ significantly with respect to the ones here considered.
 
−
 
−
Therefore, application-specific requirements have always to be taken into consideration in order to size power supply unit and to implement thermal management properly.
 
−
 
−
==== Use cases results ====

Measurements have been performed on the DWM SOM under test is equipped with:

• 1 GB DDR3L SDRAM
 
−
• 4 GB eMMC

−
1 Gbps Ethernet link has been always active during the test.
