Power consumption[edit | edit source]
Providing theoretical maximum power consumption value would be useless for the majority of system designers building their application upon BORA Lite 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 BORA Lite 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.
