————–[Power Suppy and Consumption]————–
The minimum pre-regulation voltage is 9V.
The Maximum preregulation voltage is 33V.
At 12 Volts the current demand is:
ULN-8 : 3-3.5A 2882 High Power Mode 1.5A
2882 Low Power Mode 1A
ULN-2 : 0.75A
A custom jump boot device can be be built with a pair of 9V batteries. It is used to power-on the MIO if the inrush current is too high for some macbooks to power the MIO properly.
Both the 2882 and ULN2 can be bus powered, the ULN8 will pass bus power, but does not provide it. (it must be connected to a computer to power a MIO downstream)
the minimum power requirement for the 2.1mm on the ULN8 is 16V
the minmum power requirement for the 4pin XLR plug on ULN8 is 12V
