Try it and see.

way up high at the top of the code:

#include "soc/soc.h" // Disable brownout problems
#include "soc/rtc_cntl_reg.h" // Disable brownout problems

first line of void setup:

..WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); //disable brownout detector

24

For very good reasons, most people choose to use an adequate power supply, rather than disable the brownout protection.

So i found this batteryholder

I wanna know how do i connect this to my esp32cam? Will a female juming wire help? Also will disabling the brownout detected accualy help i just wanna see if my project will even work

26

Do i just paste everything from this code at the top in arduino ide?

27

note the line that says

first line of void setup:

paste the code that follows as the first line of void setup()

hey i measured the ouput the fdti gives and it is indeed a insufficient current it puts out of 47mA while an esp32-cam needs atleast 200mA can i use a capacitor ? i am going to use a external power but delivery takes a week and maybe this will work to just be able to program the esp32-cam?

29

and is this safe? doesnt this message warns me that i should provide a sufficient voltage?

brownout does not mean insufficient voltage. brownout means the current demand is momentarily so high that the voltage drops. this Semtech designed software gives the device time to get past the SD card startup, which is a brief big current draw.

thank you i used the 3.3v but an external power source with 2 1.5v batteries
