hi
i have an issue with powerering an esp32 from battery 18650, and also a temp sensor that i draw power from one of the ports on the esp32.
the temp sensor draw 3.3v.
When i i have this setup connected to usb it works great, but when i use the battery there is not enough power. and is obvious something basic that i'm missing here..
when i connect from battery to the esp and remove the sensor it seems to be working.
is it not enough voltage i have from the battery, or amperage?
and if its volt, how would i handle it?
and if i add more voltage to this setup and if i turn off the port to the sensor, then i would get to much voltage to the esp and it will die right?
im not sure how to proceed with this ?
