USB-C Power Back for SAOs

Made for DEFCON34: the USB-C to SAO Power Back (5V to 3.3V). It lets you run your SAOs without needing a host badge, which is great if you just want to display one on your desk or shelf. You can power it using a standard USB wall brick or a portable battery pack. It can even handle powering multiple SAOs from an SAO totem. It runs three #NoICE, or Not Just a Crosswalk, SAOs with no sweat, whereas a regular CR2032 battery doesn’t have enough juice to power all three at once.
