Hello
Thank for all information and excuse me for my misspelling (PCB, capacitor).
Ok then I can consider JP12 and "delete" JP1. I would like to have a JST connector with a Li-ion battery always plug. When I plug the USB cable it's charging and power my project. When I remove the USB, the battery power my project.
Ok I understand there is no VCC. Then if look at the power cell file http://www.hello-web.net/temp/PowerCell.pdf, there is two schema. The Pin 3 of U1 should be wired to pin5 of U2 are they are VBATT.
Isn't?
And JP2 will power my project.
I do not want to have my project in 3.3V. I suppose I can delete R1 and wire R7 and R6.
I just discover something else. I can read GND and GND1. GND should be the GND of my Li-ion, but then GND1?
Thank for all
