Whoops, two corrections here sorry, iUltra9-285K takes 355W peak (not 255W), and is 4x (not 2x) faster than rPI-5 at 50x more peak power consumption, all work and no play makes tom a dull boy :D Anyways, if you look at current PC's power supply (i.e. 1000W) idle consumption of a computer that is shut down it equals to peak power of SBC doing the same job as working computer :D -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
