Esp32-c3 power consumption?

[josephchrzempiec]

Hello I been trying to figure out what the Power consumption for the Esp32-c3 module is without the bluetooth and and wifi just the processor only. I been trying to look at the datasheet and I can not figure out what it is. Can someone help me to figure this out?

Section 4.6 should have the information you need. I think, however, these measurements are for the ESP32-C3 "chip", and not the values used by a "devkit". The standard devkits used the 1117 LDO power regulator which is very wasteful.

Hello, I did look at that before and it only talks about rx and tx power and below that is for sleep. I’m just looking for cpu power only not for WiFi or Bluetooth.

Table 17, item 'modem sleep' gives you the closest estimate of the figure you're looking for.
