ESP32-S3 current consumption with radio disabled

[rtborg]

Hello,

I want to use ESP32-S3 for a device which makes no use of WiFi ad Bluetooth, so I'll keep them disabled. My question is what would be the expected current draw with the radio disabled? Trying to figure out my power supply requirements.

Hi rtborg,

You can find this information in the ESP32-S3 datasheet, Table 4-9 "Current Consumption in Modem-sleep Mode". (Modem-sleep mode is the mode where the radios (modems) are turned off. That's your case.)
The numbers range from 13mA to 107mA, depending on the CPU frequency, which peripherals are enabled, and what the CPUs are doing. For example: if the CPU frequency is 80 MHz and both cores are running, the current consumption would be in the range of 33 to 47 mA.
