[Help] USB Hub

[skrapps914]

So I had this hub laying around. Opened it up the board is pretty small. I disconnected all wired, desoldered the DC power input.

I'm working on my first GB0. New to this all.

Looking for guidance as to where I'm supposed to solder the power wires to power this up

Thanks!

It'd be cool if you could also use the card reader that is built into it. Then you could have a pi with 2 different cards to mount potentially. I'd probably have one running retropie and one running raspbian lite vanilla for web browsing/multi-media playing, not sure how you'd add a boot menu for selecting which of the cards to use though.

That is why you should take photos before you desolder everything.
I am not really sure what you want to achieve but
the Power and GND pins are clearly labelled as such on your board (lower left corner on your picture).
5V for red wire and GND for the black one. The other two are for data iirc.

It looks like the sets of pins in the four corners are for the usb ports, and the one at the bottom is for input.

But yeah, taking a picture in beforehand in the future helps a lot, as @Fleder suggested.

I found that if I powered my usb hub from my power breakout board , rather than the Pi, it was much more stable.
More than 2 devices attached to the Pi-powered hub and the Pi would glitch to reboot
