Power Consumption

The following measurements we made using Windows Embedded Compact 7. They were done on the Opal Development Kit however only the power used by the module is shown. The Windows Embedded Compact 7 BSP has not been optimized for lowest power in SUSPEND mode. This is something that is specific to each base-board and must be customized in order to achieve the lowest power possible.
