Evaluation board (79 x 46 mm) includes the AEM20940 QFN28, its 7 passive components and an external coldstart circuit to get started at 60mV. Jumpers are used to define the MPPT ratio recommended for the harvester and the protection levels recommended for the storage element.  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 thermoelectric generator harvester.  Support is provided in the Quick Start Guide and more technical details are provided in the User Guide.
