Hello, I been trying to figure out how much power does it take to run just the Esp32-c3-wroom-02 without bluetooth and wifi just the processor by it-self. Also with the bluetooth. I'm working on my own version of a smart watch. I'm learning about the light sleep and deep sleep states. It is very confusing coming from a hardware background not much on software but I'm learning.

I searched online and saw many different search pages telling what the power consumption is for full wifi and bluetooth. But not just for the processor by it-self without the wifi or bluetooth on it. I sometimes just want only the processor by it-self or the processor and bluetooth. But I will not use the wifi. That is the next thing I'm trying to learn how to disable it. From what i'm reading it still draw a good amount of power even in a standby state.

Can someone please help me to figure out what type of current does the processor by it-self take and what does the processor and bluetooth take please?

P.s.s I'm very bad at reading datasheets trying to understand it. I know I have a lot to learn.

As far as I know from other tutorials, ESP32 in deep sleep consumes 10uA. In light sleep it consumes 0.8mA. In both of these modes, bluetooth and wifi are turned off.

Hello, do you know how much current does the processor take by it-self? Is there a light sleep for the esp32? I found deep sleep. Thank you for the reply back.

"ESP32-C3 contains the following power saving modes: Light-sleep, and Deep-sleep." You will find this information here: https://docs.espressif.com/projects/esp ... modes.html

I took the info about power consumption from here: https://lastminuteengineers.com/esp32-s ... nsumption/

I think, if you write equations for all the different modes, you will be able to figure out how much the ESP-32 core processor alone consumes.
