I am currently trying to find a way for an ESP8266 mini board to be automatically powered by either a battery or a solar panel.
I found this...
and it ticked all the "boxes" that I was after for this project (the battery side) but I have one issue with it...
It is based off of a 6V solar panel but what I will be using was measured as a 12.5V solar panel.
can someone help me in how I should make it possible as the solar panel was from an old kit.
and if possible is there a way It could "split" the solar output between the board and charging the battery (when it needs to top up) at the same time?
