This is my last revision which a did so far.

It contain following parts:

Charging & auto reset circuit is copy of same circuit which Adafruit have on Adafruit Feather HUZZAH with ESP8266 WiFi . USB to Serial part is from Nodemcu github documentation page. Because I want in the future monitor battery voltage (when board is not connected to power source), I placed 2 resistors on analog input of ESP and connect it to battery positive contact. This way I can monitor how much voltage is comming from battery and possibly send message that battery should be connected to power source.

Here is schematic:

Board design:

Here is how board look when is populated. Both previous revision have wire connections, this board is double sided becuase it would be to many wire connections.

I assembled board in this manner:

So far so good. Here is how fineshed board look like:

Ok, board is working, but is everything OK? No.

Here is more pictures of finished board:

Conclusion

Revision C board is finished and I think it is success. If I want simple board which will have same functions as orginal project from Squix78 and Ruiz Brothers it would be done, but so far I completed 3 from 7 tasks.

Thanks for your time with my project and that´s all for this revision, if you have any question, let me know in discussion ;-).
