Evaluation board (79 x 46 mm) includes the AEM10941 QFN28, its 7 passive components and jumpers used to easily configure the AEM. Jumpers are used to define the MPPT ratio recommended for the harvester and the protection levels recommended for the storage element.
Additional jumpers and resistors footprints are available for additional features. See the online configuration tool for further support. Screw connectors allow the user to connect simply and quickly the load to the HVOUT/LVOUT LDOs output voltages, the rechargeable storage element, the primary battery if used and the photovoltaic harvester. Support is provided in the Quick Start Guide and more technical details are provided in the User Guide.
