The micro solar power manager is a solar power management module that supports the MPPT algorithm and has stabilized output. It is compatible with small solar panels ranging from 1V to 3V. This battery-protected solar power charger is designed specifically to power low-power wireless sensors or controllers in IoT systems. When combined with BLE Sensor Beacon or other wireless sensors, it can create a long-lasting solar-powered wireless sensor node. Additionally, when combined with the FireBeetle ESP32 series controller, it can greatly extend the device's usage time, taking advantage of the ESP32 series' low power consumption capabilities. With the micro solar power manager, customers can easily integrate their solar power supply systems and provide continuous, stable, and eco-friendly energy for their IoT projects.

This solar power management module boasts a voltage regulation output of 3.3V and 90mA, effectively meeting the power requirements of most low-power devices. It ensures the stability of the power supply during wireless device data transmission and reception, preventing system crashes caused by sudden electrical surges. This is particularly critical for sensitive precision instruments and sensors, for which high stability is of utmost importance. Furthermore, the voltage regulation output also minimizes device malfunctions and damages that ensue from voltage fluctuations, thus prolonging the lifespan of the equipment.

This solar management module utilizes a constant voltage MPPT (Maximum Power Point Tracking) algorithm, which enables maximum solar energy conversion efficiency even in low light conditions. It can charge a 3.7V lithium battery via both solar panels or USB, supplying up to 70mA and 100mA charging current respectively.

For low-power solar projects, when faced with consecutive cloudy days or insufficient battery capacity to meet equipment requirements, the lithium battery may suffer from over-discharge problems. To address this, the micro solar power charger is designed with overcharge and over-discharge protection features, which ensure that the battery is kept within a safe range during charging and discharging processes, thus prolonging the battery's lifespan.
