Power off peripherals reduce power
Posted: Sat Jan 14, 2023 9:33 am
Hi. Is there a tutorial to teach me how to turn off various peripherals?
My ESP32 seems to get hot, in fact, I think one failed due to overheat.
I'd like to completely power down the Bluetooth module, and maybe run the WiFi at a lower duty cycle.
Also, if there is a way to turn off the SCI or the serial interface for a time that would also help.
I am using 16 LED's (most are off) would it be helpful to set the GPIO as inputs when the LED is off to further conserve power?
Perhaps another idea may be to put a heat sink in the can. Will that adversely affect the WiFi and/or Bluetooth?
Thanks, Mark.
