#383 Cheap and simple Solar Power for our small Projects (ESP32, ESP8266, Arduino)
Why people recommend it
Cited to explain why running a load while charging through a TP4056 causes trouble, and how a power path modification fixes it in small solar projects.
Watch for: Suits low-power microcontroller projects on lithium cells
In their words
The project was inspired by a solar charging circuit from one of Andreas Speiss's videos ([video]) where he added a "power path" so that the load (in my case the nRF52840) runs directly on solar when there is sunlight instead of discharging the battery.
