Question

How much power does Arduino draw?

Answer 1

The lowest current consumption has the Arduino Pro Mini with 1.58mA. We could reduce the consumption for the Arduino Pro Mini 3.3V by 69.20% and for the Arduino Pro Mini 5V by 89.19%.Jul 26, 2020');})();(function(){window.jsl.dh('10','

TL;DR: To reduce the overall power usage of the Arduino UNO board significantly:

1. replace the linear regulator with a DC-DC converter,
2. adjust the USB-to-Serial circuit so it's only powered from the USB port,
3. cut out (or desolder) the always-on LED's on the board,
4. use the processor sleep mode.

The board can operate on an external supply from 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
