    Hi,
    I just bought a Shelly Button1, because the ready hardware looks really nice, but
    I would like to make my own FW, in order to have some custom buttons functions, LED colors, etc..


    I found a photo on GitHub where is possible to see a STM32L031 w/ 28pins and the ESP8266
    on the Shelly Button1 board. Sounds that the STM32 is controlling everything (baterry, button, LED) and the ESP8266 is
    only used for the WiFi communication. My idea is to create a new FW for both devices.


    Is it allowed/possible that someone tell me what is connected to each pin from both controllers?

    This info will save a lot of hardware debugging time :)

    Many thanks in advance!
