== Introduction ==

−
IGEP boards have been designed using low power consumption technologies. Like other embedded devices, some system parameters like: CPU speed, CPU load, peripherals enabled/disabled, Kernel configurations and other ones, can vary its power consumption.
 
−
 
−
This article is the result of some analysis implemented to IGEP boards.
