4-Port Stackable USB Hub HAT for Raspberry Pi Zero V1.3 (with Camera Connector) and Pi Zero W /2W (with Bluetooth & WiFi)

Works as advertised. Installation instructions are in the product description. Very easy.

I put this on a Pi Zero 2 W I was using for RetroPie build to allow for multiple controller connections. Worked great -- plug n' play.

I love the 4 USB ports on the board. Great price, it costs a little less than a happy meal. No soldering or wires to connect the USB hat to the Raspberry Pi Zero. Five years ago I wondered what was next for computers. Well here we are, very small, cost effective, user friendly. Connectivity between the Hub Hat and Raspberry Pi Zero was engineered very cleverly. It uses spring loaded pins that make contact on the back of the Raspberry Pi Zero and ( W ). Get one, you will love it.

This is an elegant and compact solution to adding USB ports to your Raspberry Pi Zero. I am deducting one star because of the lack of adequate information on how to connect the HAT to the RPi Z for newbies like me. Once I contacted customer support they helped me figure out how to connect it but it ended up being that the unit I received was defective. Seller's customer service promptly replaced the unit and this is working fine now. I'm happy with it now.

I am editing my old review because I was wrong. You have to make sure the Pi Zero is NOT in OTG mode for this hat to work. If you have it set to OTG the Pi Zero acts like a slave USB hub and the hat does not work. The Pi Zero must be in the master USB hub mode for the hat to work correctly. I discovered this the hard way.=== Old Review ==I recently received this hat and installed it on a Pi Zero W. Long story short, the USB ports on the hat didn’t work. Perplexed, I tried two other Pi Zero 1.3 but the USB ports still didn’t work. It’s installed correctly so that’s not the problem; power applied through the hat’s micro-USB port. Randomly I discovered the ports work if I plug anything into the USB OTG port; they don’t work if I plug them into the power OTG port. When I mean anything works I really mean anything: even plugging in a simple OTG to USB-A adapter (with no device) makes the USB ports on the hat work. I’m really confused.... so far the product sucks.

I'm using this on my Raspberry Pi Zero 2 W so I can get some USB support to my in-dash car audio unit. I'm testing out two of them and so far they're great. We'll see how they all do once summer hits and under dash temperatures reach "don't touch that" levels.These come with plastic stand-off pieces so I swapped them out for brass/copper/metal just in case the heat makes them weeble wobble.(Edit) I've noticed that if you choose to try to also use the Micro USB port on the Zero 2 W it 100% disables the USB hat (bottom?). I've been trying to get my RPi Zero 2 W to boot from USB and after a few hours, I've learned that for some reason, when plugging anything into the micro USB port, it zeros out all the useful full sized USB ports on this board. "Back to the drawing board for me".Would recommend.

great design, great product, great quality. Uses zero of the GPIO pins, leaving the bus free for an a/d converter or anything your heart desirese. Assembles in less than 5 minutes.The only way this thing could be better is if it had an audio interface on it, then it would be instant streaming radio for the masses.Its so much easier to work with than an external usb hub, and so compact. I've bought two so far and they are both great.

Mea culpa! I returned one of these after it did not accept a simple USB game controller which disabled the already-connected mouse. The problem was my cheap "RPi4 compatible" power supply which BARELY powered the board with nothing else connected. If a bunch of stuff stops working at once, suspect the power supply! When I realized my error I re-ordered this item along with a RPi-branded power unit which is HONESTLY rated at 3A. This USB hub now works perfectly, and I really like the clever attachment method using pogo pins instead of wrap-around connector boards.
