DFRobot DFR0579 Solar Power Manager Micro
DFRobot DFR0579 Solar Power Manager Micro is a micro-power, high-efficiency solar power management module. This development tool is designed to power IoT-based wireless sensors or controllers with 1V~3V small-size solar panels. The DFR0579 development tool can maximize solar energy's conversion efficiency under weak sunlight. These features allow low-power wireless devices to be charge-free and battery replacement-free by pure solar power. This power management module employs a constant voltage ratio Maximum Power Point Tracking (MPPT) algorithm to maximize the output power of the solar panel under various sunlight. Applications include a wireless sensor network, BLUETOOTH® iBeacon, and solar-powered toys.
