What the port face looks like. We've got USB-A for 5V power out, and a mini USB for control. 12V can be drawn from either a PCIe 6-pin jack or a 2.1/5.5mm barrel jack (for running off a brick). The blue knob is used to adjust core voltage from about 0.63 to 0.80V chip-level, basically the same range as the 2Pac. It can be assembled with a vertical (pictured) or right-angle (front-facing) adjuster.
