AEMLION: Solar harvesting into Li-ion battery


The AEMLION is a highly efficient solar powered Li-ion charger with two regulated outputs by Jasper Sikken. This is the sister board of the AEMSUCA: Solar harvesting into supercapacitors.

The AEMLION is a 0.8x0.6 inch (20x15mm) PCB with the AEM 10941 Solar Harvesting IC from E-peas. It efficiently converts solar energy into Li-ion battery charge, it even works with indoor light. It features 3.3V and 1.8V regulated outputs that are enabled when the battery has useful charge and a low battery warning that informs the user of impending shutdown when the battery runs low. It easily integrates into other projects because of small size, castellated via’s, and when soldered onto 0.1" pitch header it fits in a breadboard.
