What’s your power adapter? 5V?

#3

5V/2A mobile charger

Change it to 9V/2A or 12V/2A, or use a USB PD power adapter.

Okey but i will connect POE hat later but ROCK PI headers accept only 5V right??? i cannot give 9V/2A to the 40 pin header on rock pi for time being i’ll use USB whats the solution for that when i supply power through header???

If you power from the GPIO header, you can only use 5V. If you power from usb c, you can use 9v/2A, 12V/2A or other PD/QC power adapter. If you use PoE HAT, make sure use the 23W ROCK Pi PoE HAT, which provides enough power for the board and the usb camera.
