@felmue You're absolutely right about VBUS. When I flashed the example firmware from the Arduino IDE, the power supply worked normally. However, the factory firmware did not. How the hell is it possible that such a thing isn't described anywhere in the documentation? Thank you, you really helped me a lot.

@felmue Both are UiFlow2, SE version arrived today, so factory firmware. Do you have any suggestions?

I have a problem with the power supply for CoreS3 and CoreS3 SE. It is always manifested in all 3 cases just by flashing the backlight on the display every approx 3-5 seconds.

My power supply is not working when using:

• PoE using "LAN Module W5500 with PoE V12"
• DC jack power supply 9 - 24V on "LAN Module W5500 with PoE V12"
• DC jack power supply 9 - 24V on RS232 Module 13.2 with DB9 Male Connector (M131).

I tried 2 different pieces of "LAN Module W5500 with PoE V12" and also CoreS3 and CoreS3 SE but it behaves the same.

In the documentation on docs.m5stack.com it is not mentioned anywhere that the LAN module with PoE or RS232 module should not be compatible with CoreS3 or CoreS3 SE.

What is wrong with this?

Hello,

can you please explain this documentation for DIP switches settings on GNSS module? How I can set it for the Core 2? DIPs are 0 or 1 but table has 3 columns.

Thank you
