@elefas-GR DOOM next, right?

Never mind. Answered my own question: https://docs.onion.io/omega2-docs/hardware-prep-no-dock.html

I would like to power the omega2 directly without a board. I understand it needs 3.3v input, of which there are no standard ones to purchase.
Would I just be able to use a standard usb cable (5V) w/ this 3.3v downstep from Banggood (https://goo.gl/zeb2eJ) to directly power the omega2?
