An effective solar energy harvesting solution requires more than just a solar panel. 


That's why we have partnered with e-peas, an energy harvesting PMIC solution provider, to launch our new Indoor/Outdoor e-peas Solar Development Kit.


With the e-peas AEM10941 PMIC and our new compact solar panels, the AEM-PF-EVK delivers industry-leading performance and a platform for developers to design, test, and prototype solar energy harvesting solutions for low power IoT devices and remote electronics. 


Editor-in-Chief of Embedded Computing Design, Brandon Lewis, unpacks the Indoor/Outdoor e-peas Solar Development Kit.

The AEM-PF-EVK makes integrating indoor solar into electronics simple. It includes e-peas' high-performance energy harvesting PMIC with integrated power management designed and optimized for PowerFilm’s thin-film indoor and outdoor solar panels.


Efficiently extracting energy from the solar panels, the AEM-PF-EVK can store energy in a rechargeable element while 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. 


The AEM-PF-EVK is an ideal power source for any low power electronic device, especially those in emerging IoT applications such as BLE beacons, trackers, sensors, ESLs, RTLS, telematics, wearables, smart locks, thermostats, livestock monitoring, and industrial automation.  


Differentiating Features


Energy Harvesting PMIC

  • Industry-leading boost converter efficiency (95%) with ultra-low global leakage (400nA).

  • Lowest cold start power and voltage available (3uW at 50mV).

  • Small PCB footprint with only seven passives.  

  • Dual cell Supercapacitor cell balancing circuit and landing pads.

  • Dual low and high voltage power output rails.

  • Primary battery backup option. 

  • Custom charge profile options.  


Thin/Flexible Solar Panels

  • Smaller size/form factor to better serve small, ultra-low power devices. 

  • New higher-performance "fingerless" indoor material with reduced interconnect shadowing. 

  • Ultra-thin, flexible, and highly durable.  

  • Many custom sizes, options, and configurations available based on application requirements.


With high-performance thin-film solar panels and industry-leading energy harvesting PMIC, the AEM-PF-EVK is the perfect platform for developing a solar energy harvesting solution for low power electronics and IoT devices in indoor and outdoor settings.


With the right tools, anyone can use light energy to enable innovative, perpetual IoT devices that are not limited by a finite power source.
