Core S3 and DMX Module power problem [SOLVED]

  • T

    If I use the power jack on DMX with a 12V power supply the S3 LCD is flashing without boot.
    Any suggest?

  • Hello @Telmo

    your M5CoreS3 probably is running firmware with sets the 5 V as an output as soon as it starts to run, causing it to reboot again and again.

    You can try to add below line after M5.begin(); to make sure 5 V is set an input.

      M5.Axp.powerModeSet(POWER_MODE_USB_IN_BUS_IN);

    Can you share the code your are running?

    Thanks
    Felix
