USB Hubs
Want to integrate a 7 port USB hub into your Raspberry Pi project, but don't want to rip one out of a pretty plastic case? Don't worry! We've got our hands on some stripped down, "naked" USB hubs which work great with the Raspberry Pi!
They have some pretty special features too. . . . .
- Fully tested for compatibility - plug and play!
- PCB footprint is very close to the Raspberry Pi - 6mm overlap on length & width
- Each hub is able to sufficiently back-power a Raspberry Pi Model B.
- If you don't want to back-power your Pi, it is very easy to modify this hub to stop - Tutorial below.
- Each hub includes a 5V 2.5A UK power supply (EU & US adaptors available)
- Each hub includes a 0.5m USB A to Mini B cable.
- We've drilled some M3 holes for mounting (in addition to the M1 corner snaps)
- There's no solder mask (so you can hack it all you want!)
- They're also white, which is sexy!
- Mark Peason created a 3D Printable Case for the Naked Hub!
- Paul Kersey-Smith created a Laser Cut Case for the Naked Hub & Pi!
Please Note
- This hub is sold for development purposes only
- This hub must be connected to your Raspberry Pi at boot
- This hub comes with NO warranty once modified

How to Modify Hub Back-Power Capability
Back-powering on the Raspberry Pi is the mode of powering your Raspberry Pi via the 5V line on a USB port (as opposed to the Micro USB power port). This is a very effective way of reducing clutter when using a USB hub with your Raspberry Pi, as it essentially means you do not require a separate power supply for the Pi itself.
All Raspberry Pi's after the Model 1B+ DO NOT allow back-powering
If you don't want your Naked hub to back-power your Raspberry Pi then you need to short the 5V line from the hub somehow. You can modify your cable (just snip the 5V line) or the hub! We've modified the hub below:
Get a pair of needle nose cutters and snip the Vcc line as denoted above (be careful of the other lines!)
That's it - break the circuit from the Mini USB port and you're done - no more back-powering!
This is a 4-port USB 2.0 hub for Raspberry Pi Zero, and it can be mounted to Raspberry Pi Zero back-to-back.
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 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.
