ESP32 CPU frequency

Postby salomonreinach » Fri Feb 08, 2019 4:16 pm

Hey ! I would like to know how I choose the frequency of the esp32 (I mean when I have to choose 80,160 or 240Mhz ?).

And also most important, is there a really change in terms of energy if I choose 240Mhz instead of 160Mhz ?

Thanks :D

Hi,

You can select CPU frequency from menuconfig. Of course if you choose higher CPU Frequency then it will definitely consume more power means current compare to lower frequency.

Default example is 240 MHz for CPU frequency into default config file.
