A more sophisticated and accurate way of measuring energy consumption consists in using a power profiler, such as the nRF Power Profiler Kit and or the Otii Arc Pro. One advantage of For this tutorial we selected the latter is that , since it is designed to be board-agnostic , so we will select it as the instrument for this tutorialand also allow interacting with GPIO pins.
