ESP32 Forum

Hi,

I wish to understand whether I can use any one of ESP32 series modules with battery, considering Light Sleep (130uA) and Deep Sleep (5uA) current consumption. Here I am considering battery of type CR2450 type.

Here please note that I do not want to use Wi-Fi at-all.

Also I have heard that ESP requires more power at start-up so one can not power it from coin cell.

Please guide.

Regards,

Dinesh

Power use as detailed in the datasheet is mostly determined by WiFi currents, and we figured out you need something that can deliver 500-600mA of power to start the ESP32 correctly. Unfortunately, we don't know the power requirements if you don't start WiFi (or BT), so you'd be on your own there.
