Crowd Supply makerPower Solar
Crowd Supply makerPower Solar is an intelligent solar power system ideal for Internet of Things (IoT) projects. The makerPower Solar combines a solar battery charger and a 5V power supply, enabling technical professionals and hobbyists to take their embedded systems and IoT devices off the grid and run them anywhere. The makerPower Solar can operate as a simple stand-alone power supply or as a peripheral capable of fully reporting power conditions. A true Maximum-Power Point (MPPT) algorithm extracts every joule of energy from all solar conditions.
