Editor-in-Chief of Embedded Computing Design, Brandon Lewis, unpacks the AEM-PF-EVK Solar Development Kit with e-peas PMIC (DEV-EPEAS).


The AEM-PF-EVK Solar Development Kit with e-peas PMIC (DEV-EPEAS) makes integrating solar into electronics simple. It includes an e-peas high-performance

energy harvesting PMIC with integrated power management designed and optimized for PowerFilm’s thin-film indoor and outdoor solar panels. Use Indoor Light

series panels for indoor applications and use Classic Application panels for outdoor environments.


The AEM-PF-EVK 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.


See Quick Start Guide for details on configuring storage element type and other board options.

Indoor Series


Classic Application

MPT2.4-21 25% &100% Sun Electronic Component Solar Panel IV Curve



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.
