Page 18 of the AXBB-E manual indicates:

We recommend to use a power supply with at least 500mAmps of current capability of the
power supply. More current may be required if more I/Os are used on the unisolated port
and on the IDC26 port.


I selected a power supply that is rated for 1 Amp so I should be good. I don't use any IDC26 extension ports.
