      @arzaman Really sorry about that. I do not clearly know your problem.

      "-if I disconnect USB using core bottom battery the core stays on and I can do reset with power on again
      -if I power off (double click) no change to power on again"

        @arzaman I apologize for the misleading on schematics, it is surely our mistake, we didn't well organize all of the material. We are working on it, will have better material come out soon.

          @m5-docs I think we can conclude that is and "HW failure of IP5306" no big issue I can use this core for the lab or for application with no battery

          maybe if you can send me a replacement or tell me where to buy the I2C version of IP5306 I can try to replace by myself

          thanks for the support anyway

            @arzaman The IP5306 which is iic version is customized. The best way for you is to ask saler for a replacement or ask our saler for a new core or iic version IP5306. Sorry for the inconvenience !

              @liushasha no problem...I had an old schema and did not check the note you add to the new one. Your documentation level is quite good and indeed If there is a problem I see there is quite good support on the forum and community ... in a way or another I get the info :-)

              most important that now I have more understanding of power management and the fact I can control battery via SW is very important (M5stack is perfect for portable applications battery pwered)

              could be VERY USEFUL a sort of translation of IP5306 Chinese data sheet
              there are few register that provide info but not able to unerstand the usage !!

              from various source I undertand that
              0x78 provides battery level (25/50/75/100)
              0x71 battery charging level (but not sure)
              what about the other registers ? what about control register ??

              simple table with register and functions/value will help a lot "non Chinese" speaking people
              hope to see soon in the documentation !

              thanks

                    If you are getting an understanding of the power management of the IP5306, would you mind helping me write it up for my book please?
                    You will be credited for the information in the book.
