ESP32-WROOM-32D/E deep sleep current consumption?

Postby mitchk » Fri Jan 19, 2024 3:04 am

What is the expected Deep Sleep current consumption of the ESP32-WROOM-32D (or E) module? In the datasheet I can only find reference to the ESP32 chip that its sleep current can be as low as 5uA. I cannot find the same information for the module. Also if the numbers are different between the D and E module I'd like to know that as well. I am currently working on a board that uses the D but will migrate to the E with the next design. Thanks.

I assume the deep-sleep current consumption is the same for all versions of ESP32. That's why they do not specify anything in the datasheets. Let's see if the admins here say otherwise.

To try and find this answer myself I populated one of my PCBs with just the ESP-WROOM-32 module and the minimal components around it and then ran the "deep_sleep" example code from IDF 5.1.1. With the module in the deep sleep state the PCBA was consuming 44uA. For comparison when the module is held in reset the PCBA is consuming 5.9uA. Note that this is not a D/E version of the module it is an older one that I happened to have on hand.
