The following is the start of a series of tests regarding minimized consumption mode for SBCs. Idea behind is to provide Armbian settings that allow some of the SBC we support to be used as cheap and low-power IoT nodes (or call it 'home automation' or anything else, at least it's about low-power and headless useage)   I start with some consumption comparisons with various RPi models below just to get a baseline of numbers and to verify that my consumption monitoring setup is ok.
