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 as 2.5A USB PSU => Pi3 => AD2. I also get a "unsufficent power". I've tried a few different USB cables too.
The USB 2.0 spec, according to Wikipedia is 5V +/- 0.25V, so anything above 4.75V should be possible. Is there any hints?
If I wanted to make a USB dummy load and test the voltage drop, what specs should I be checking for?
