Simplest way to turn off load cell connect to lilygo board
I have an hx711 connect to 3.3v PIN of the board, but drains too much Power, Is there a very simple way of cutting the Power from 3.3v PIN going to the hx711 powering the load cell? A switch that can be turned on and off using a command free PIN of the board. Thanks

(I keep reading 8388608 value) https://github.com/bogde/HX711 Lowering the frequency of the esp32 seems to create new issues and othe...
