I was asking myself wether it's possible to power my nodemcu board (version 3) with a usb powerbank, like a smartphone, but the powerbank should then be recharged by a solar panel. So this is basically like it could look like:
I know, there should be some charge regulation, but i would just like to know, if that circuit would be able to charge the powerbank? According to the Hardware Layout, it could be possible, but i am not definetly sure about that. Maybe you can give me some input about that.
