I'm trying to use a 5V 2A power bank to drive a small LED matrix at low brightness and I'm having trouble figuring out what this is. Am I missing something?
I've searched for "USB to molex" and "USB to small molex" and all that and get absolutely nothing, just USB to 4 pin molex with the angled corners and round pins or a black male fan connector of some sort. What's a reasonable way to connect this to USB?
This was the setup I was hoping to be able to do, using a Pi and https://github.com/hzeller/rpi-rgb-led-matrix:

Thank you.
