ESP32 Forum

I would like to know if it was possible somehow to keep connected the micro usb of the esp32-cam-mb to load the module and in the meantime check the consumption(Ampere) from a multimeter.

i tried to connect the multimeter in any way but failed

Thanks

Sure. Take an USB lead, cut off the outer isolation, find the red wire, cut it in two, connect multimeter in between. Make sure the internal resistance / burden voltage of your multimeter is not too high: if the voltage drop of the multimeter is too high, your ESP32 may brown out. (You can try switching to the 10A range when you think that happens.)
