So I made a quick little USB power connector, to experiment. However, I'm not getting anything like this.
When I power through the pins on the board, (Vin and GND) I get a voltage out of the USB connector. It's fluctuating between ~1 and ~2 VDC. However, when I try to power through the USB, as shown in the picture, I have no power, when tracing the 3v3 and GND pins.
I get 5VDC when I take a reading off of the screws in the terminal block.
