Hello, I am trying to make less power consumption for nodemcu. I know there is a sleep mode we can use but I need to go deeper. I want to cut off the power somehow. I was thinking make with timer. I will send data to timer for setting a time. When the time comes it will send to 3v signal to mosfet and it will open the gate for power. The problem is with timer. I really don’t know now is there a timer for my purpose.
Also i tried to draw on excel what i was planning.
