“Bought it for my Raspberry Pi Zero 2W to give it some proper USB ports for KB and mouse etc. Sadly it isn't compatible with the pins so the Zero can't wear it as HAT (none are compatible like that as far as I can see at this time). But you can screw it underneath easily enough and connect it directly with a male to male micro USB. Obviously due to the limited power and capacity, this is only good for devices like touchscreens and other input peripherals.
The hub is well made and reliable. No sure what else I can say!”
“This is a neat little gizmo that upgrades your micro-USB port on a Pi Zero to support 4 USB 2.0 ports. Very useful if you want to attach devices like a mouse, keyboard, printer or storage device to your Pi Zero. The hub needs to be powered using the supplied USB cable but is a cinch to set up. If you have soldered a header on, the hub neatly slides over this.”
