ESP32 Power consumption considerations

[rustyx]

A better approach to testing current draw is to get a ESP32 Test Board. Like one of these. With the ESP32 removed test the current draw of the board alone. Then pop the ESP32 in there and subtract the new reading from when it was removed.

That board has the same linear regulator as other boards. It will draw the same current at 5V as the chip does at 3.3V (and dissipate the difference). Roughly speaking you'd have to mutiply the current by 0.66.
