The Solar Devboard V1 Keeps Remote Sensors Alive
Occasionally topping off the battery in a development board that is being used as a smart home sensor is a mild inconvenience. But when that sensor is in a remote location — especially if it is part of a large network of sensor nodes — keeping everything charged can quickly become a nightmare. As an alternative, many such devices are connected to a solar cell to keep the battery charged without manual intervention. The problem with this approach is that it introduces a lot of extra hardware and complexity into the equation.
Andrei Pokotylo developed the Solar Devboard V1 to address this issue. It is equipped with an ESP32 microcontroller and all the other essentials you would expect from a basic development board. But in addition to that, it also has all the circuitry that is required to safely charge a battery from a solar cell right on the main...
