AEM-PF-CAPXX-EVK Solar Development Kit with e-peas PMIC and CAP-XX Supercapacitors (DEV-EPEAS-CAPXX) makes integrating solar into electronics simple. It includes an e-peas AEM10941 high-performance energy harvesting PMIC, PowerFilm’s thin-film indoor and outdoor solar panels, and CAP-XX thin prismatic supercapacitors.
The AEM10941 efficiently extracts energy from the solar modules, which can be stored in a rechargeable element while also providing two independent regulated voltages to power IoT devices. The integrated power management supports multiple storage element charge configurations, including, Li-Po, Li-ion, LiFePO4, Solid State, and Single/Double cell supercapacitors. Configurations are easily selected by moving pin jumpers to desired positions.
Use Indoor Light series panels for indoor applications and use Classic Application panels for outdoor environments. Solder on the Cap-XX devices to run your IoT device without battery.
See Quick Start Guide for details on configuring storage element type and other board options.

Harvesting indoor light with the paired LL200-2.4-37 panel provides approximately 80μW in a low light luminosity (200 lux). After eight hours of exposure, the AEM10941 harvester will collect about 1.8 J of energy.
Harvesting outdoor light with the paired MPT2.4-21 panel provides approximately 6.8mW under indirect or ambient sunlight (25% of direct sunlight). After eight hours of exposure, the AEM10941 harvester will collect about 156 J of energy.
