      Hello everybody, I'm working in a project with this amazing MCU and I have one question.
      The project consist in a system remotely programmable so I'm using the LAN module K012-B.
      As you know, this module have an addicional input supply. The question is the following. Can I power all the system by this way and if I need to reprogramming be able to connect the USB port ? The 2 at the same time. I look the schematic but I doesn't find any protective diode.
      Thank you.
      Rob

        Hello @Robertolo

        if you look at the M5Core2 schematic in the top left corner you'll find AXP192 and its inputs ACIN (connected to USB_5V) and VBUS (connected to BUS_5V). USB_5V comes from USB and BUS_5V comes from the LAN module.

        The AXP192 automatically switches between the available power sources and picks the one best suitable. Please also check the AXP192 datasheet.

        Thanks
        Felix
