Hi. I've replaced my Cubieboard with a Raspberry Pi 3, and it runs the ARM version of Waveforms really well. With an Electronics Explorer everything works sweet. With the AD2, it complains about supply and/or AUX voltage, even with a 5V 3A power pack attached (The power supply panel indicates that the AUX supply is present so I know it is working well). The USB voltage usually shows as 4.92V at a few 10s of mAs I've tried with 2.5A USB PSU => Pi3 => Powered Hub => AD2, as well
