M5stick C button PIN mapping



  • Hi

    I have some doubts and inconsistency in the documentation related to M5stick C push button mapping

    In the documentation we have
    https://docs.m5stack.com/#/en/core/m5stickc

    BUTTON A GPIO 37
    BUTTON B GPIO 39

    If I check the schematic I don’t see the mapping at all
    https://github.com/m5stack/M5-Schematic/tree/master/Core

    In the ESP Core schema there are no GPIO37 mapping on ESP32
    In the UART schema I found two buttons: one connected to GPIO 35 , the other one to EN net so PIN 5 of IP5306 / PIN3 of ESP32

    0_1567428094305_ed4261cf-fb9b-46bc-8665-3206a5191d57-image.png

    Really confuse

    More over the left button, the power ON/OFF button where is connected is the one connected to IP5306 ?

    Can someone provide clarification and provide a correct schematic ?

    thks
