The uSDC draws much less power than the Opus in the off state. The uSDC draws less than 1mA when it is shut down. It turns off the microcontroller and puts it into sleep mode (it wakes up with activity on ACC). I am using a very low Power Regulator to get the 5 volts.
I have not tested how much power the Opus uses when it is off and not powering the mobo, but I imagine it is at least 20mA just to power the OPUS, not to mention whatever your motherboard draws to keep USB, Wake On Lan, and the power button sense stuff.
Has anyone measured it on an Opus?
