ESP8266 Community Forum

first of all, Happy New Year !
So...I've built a solar powered weather station equipped with various sensors, a TP4056, a MAX17043, a 18650 2900 mAh battery and an ESP8266.
I found several wiring scheme for systems with TP4056 and MAX17043 then I wonder which is the correct one.
Everything seems to work correctly, I can read voltage and SOC of the 18650 battery that is connected.
I attached the wiring scheme that I have adopted: is it correct?
Is there a better way to connect those boards?
Thank you, regards.

The pinouts of MAX17043 are marked at the back of the board. But in your diagram, we can see the front side only. If you give a diagram showing the back of the board, I think it will be convenient for us to check.

I hope it's clearer now.
Thank you
