Core S3 and DMX Module power problem [SOLVED]

[Telmo]

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
