This version of Zero4U works with Raspberry Pi Zero V1.3 (with camera connector) and Raspberry Pi Zero (2) W (with the help from a ferrite ring, details here).
On Raspberry Pi Zero 2 W, although the DP pad moves a little bit, the move is so small that Zero4U’s pogo pin can still contact it. Please see the overlapped photos bellow (thanks to Jeff Geerling for providing the photos), the DP testing pad moves a little bit to the left, but the center of the old DP pad still within the new DP pad. We confirmed that Zero4U can work with Raspberry Pi Zero 2 W.
After complete tests we realize that Raspberry Pi Zero 2 W has stronger WiFi radiation than the first generation of Raspberry Pi Zero W. As a result, the USB devices connected to some ports in Zero4U may get interfered and work unstably. The solution is to place a metallised PET membrane under Zero4U, this material is the same with those anti-static bags in silver gray color.
Since March 4th, 2022, we put a metallised PET membrane into the package. This membrane can be placed at the bottom of Zero4U (please see picture below), and protect Zero4U from being interfered by WiFi radiation.
This is a 4-port USB hub for Raspberry Pi Zero, and it can be mounted to Raspberry Pi Zero back-to-back. After mounting this USB hub to your Raspberry Pi Zero, it immediately has 4 USB ports that could transfer data in USB 2.0 high-speed. The 4 pogo pins on the back will connect the PP1, PP6, PP22 and PP23 testing pads on Raspberry Pi Zero, hence no soldering will be needed.
The USB hub will take power directly from your Raspberry Pi Zero, so you don’t need to power the USB hub separately. However you can use the JST XH2.54 connector on board as the alternative power input port.
The blue LED on board works the power indicator, and will lights up when power is connected.
Each USB port has a dedicated white LED as transaction indicator, and a dedicated electrolytic capacitor to help stabilizing the output voltage.
If you use this USB hub with other types of computer, you can use a USB cable (not included) to connect the mini-USB port on board to the up-stream USB port.
You can also get an Acrylic case for it.
Remarks: if you ever enabled Ethernet Gadget on your Raspberry Pi Zero, you will need to disable it to use Zero4U. You can either comment out the “dtoverlay=dwc2” in /boot/config.txt, or plug an OTG adapter to the data micro USB port on Raspberry Pi Zero.

Fantastic piece of kit. Easy to assemble and works out of the box. Status LEDs are useful as well!

Amazing bit of kit, simple to assemble and just works. I have the versions for both the 1.2 and 1.3 versions of the PiZero. Its a must for anyone wanting to use normal size USB devices.
Makes the pi zero so much easier to use effectively. A very neat solution. Fits nicely in the case also available here (though it won’t fit with heatsink added).
(Speedy delivery too and great customer service from uugear.)
quite nice, works as advertised, my USB wifi dongle worked great in port-4 with the unit powered from the pi via microusb. Future purchasers should definitely read the manual here before buying, just so you know what you’re getting. Case fits nicely (although stressful to assemble) with some caveats that I’ll mention on that product’s review
That´s what everyone needs for pizero. Good product.
Worked out of the box without any problems. Fits really nicely as well.
I am very impressed with the quality of the Zero4U V1.3 USB Hub. Solid. I will be ordering more of them because I can’t imagine using a Pi-Zero without one. Thanks UUGear.
TOP Qualität! 4 Stück bestellt alle laufen! Super Support. Wurde sogar sofort benachrichtigt, dass eine neue Version des Raspberry Pi Zero rausgebracht wurde und der alte ZERO4U: 4-PORT USB HUB damit nicht funktionieren wird. Das Geld wurde zurück Überwiesen und nach nicht mal einem Monat eine neue Version des ZERO4U: 4-PORT USB HUB entwickelt! Diese habe ich dann natürlich sofort bestellt! Zusammengefasst, ein toller USB HUB für wenig Geld, 4x 500mA Output Power und vielen Stromversorgungsmöglichkeiten. Was will man mehr?
I have been using this hub for some months now, and I can not imagine going back to USB adapters or an external USB hub.
It is a really great addition to the PIZero!
Just perfect. I had been struggling for a while with various usb hubs, trying to get all the peripherals to work without success. The Zero4U came along, and instantly everything was perfect. It’s so neat and seems to be well made too. The dedicated case for the Pi with the Zero4U available from UUGear is well worth investing in too. The package arrived very quickly here in Scotland, and was very well packed. A great find.
It just works, and it works great. Easy to use, fits perfectly, and zero problems with it.
A fantastic addition to your Zero, i use mine to power many peripherals turning my mini zero into a home control station. fantastic invention. The power distributes evenly and doesn’t lack in USB bus transfer speed. Brilliant piece of kit that should be in everyone’s kit-bag.
I ordered a package containing a Zero2Go and Zero4U on December 3rd and it arrived on December 19th. The packing was well done and it arrived in pristine condition. Both items plus shipping total to 27.32 USD. I am very pleased with the purchase, everything works as advertised and I plan to do business again with UUGear in the future.
The best kit for raspberry pi zero so far!! I will buy again! ^^
Super quick shipping to NZ thank you. Works flawlessly.
I very much like this hub, since it adds very useful features to the Pi Zero. Easy to install, I recommend to use the case for the Pi Zero and the Zero4U hub, which you also can buy from UUGear.
Deeraj C –
Can you please provide mounting hole dimension or this same (ZERO4U: 4-PORT USB HUB FOR RASPBERRY PI ZERO (V1.3 AND W)).
Hi, the mounting hole has the same size (D=2.75mm) with those mounting holes on Raspberry Pi Zero (W). The position of holes are also the same.
