I just received this module, and this weekend I wanted to make a small program to monitor the outside temperature and humidity, but also plug it in at 5v from a small 250mA solar panel, as a test to see if this can work continuously with only power from the solar panel (to recharge the battery).
I want to monitor the battery voltage also, and I see that next to the A0 pin on the board there are 2 resistors, is that a voltage divider, is it already connected to the ESP analog input pin ?
Anyone that can provide some advice's, or documentation for this board please reply to this thread.
UPDATE. 120 views and nobody knows ?
