Can I use the 5V power port on the ESP32 to power the sensor?

hello,everyone!
I am using a development board from the ESP32-DevKitC series, and the sensor requires a 5V operating voltage. The pinout for the ESP32-DevKitC board is as follows. Can I use its 5V power rail port to connect the sensor's VCC power supply? Because the ESP32's GPIO port operates at 3.3V, will this cause a conflict and damage my development board?

Yes. You can.

Yes, but what voltage is your sensors output voltage? If 5v as well you have to bring that down to 3.3v.

The 5V of the board can supply power to the sensor; if the sensor needs 3.3V, then it needs to be connected to the 3.3V power supply; otherwise, the sensor will be burned out.
