Hello Everyone,
Im working with Luckfox Pico Ultra W board.

Please help to review and show me a solution .
Thank you for yours support.

Hello, for P1.2 connected to 5V and P1.6 connected to GND, there is no problem. You need to confirm whether your power supply supports 5V with a current of more than 500mA.

When using both an external power supply and a USB interface for power supply simultaneously, it is necessary to ensure that the GND of the two power supplies is the same or connected. Not sharing the same ground may cause the development board to work unstably
