| − | === Power consumption === | |
| − | 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.
