Instructions:

If you don't post AT24C02

It needs to be connected to a 5V power supply first, and then connected to P2/P4/P5, so that it can be displayed normally.

Otherwise, there is a chance that the EDID will be recognized incorrectly, resulting in incorrect resolution display.

If you post AT24C02

You can connect to P2/P4/P5 first, then power on.

There is no requirement on the power-on sequence.
