The use of a USB 3.0 compatible port will ensure that current requirements for the Portenta X8 are met. Dynamic scaling of the
Portenta X8 compute units can change the current consumption, leading to current surges during bootup. Average power
consumption is provided in the above table for several reference scenarios.
