Hackable "Naked" 7 Port USB Hub - UK 5V 2.5A
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!
- 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
- Fully CE Approved Hub
- 7 Port USB hub
- 3.5A over-current protection on board
- 1.2A max draw per USB port
- Supports USB 2.0
- Includes 0.5m USB Data Cable
- Includes 5V 2.5A UK Barrel Jack Power Supply - 3.5mm OD x 1.35mm ID
- Dimensions: 95mm x 73mm x 14mm
- M3 Mounting Holes
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.
If you don't want your Naked hub to back-power your Raspberry Pi then you need to disconnect the 5V line from the hub somehow. You can modify your cable (just snip the 5V line) or the hub! We're 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!
