Qwiic Hub

The Qwiic Hub allows you to expand a single Qwiic port into four, along with an additional set of pads for using non-Qwiic I2C devices with your Qwiic-based project, alongside M2.5 mounting options, convenient underside soldering pads and an onboard power LED!

All ports on the Qwiic Hub are connected to each other (just like a USB hub), however we designed the board with a single port on one side as the obvious microcontroller ‘out’, leaving the other four ports for Qwiic sensors and devices (see the product images for an example). Another handy way to use this hub is tosoldertheincluded 4-pin headerto the board and use it as a breadboard adapter for Qwiic devices –handy!

I2C and Qwiic devices use four lines for power and communication –GND, 3.3V, SDAandSCL. The pads on the board connect these lines to the Qwiic connectors (also seen on our Qwiic Breakout), allowing you to connect non-Qwiic devices to the hub.

There’s a little blue power LED for some visual power/connectivity feedback, but if youre not into that blinky life, you can cut the highlighted trace to disable it.

We also usedM2.5 mounting holesas they’re a popular size with easy-to-sourcefixings…because who in their right mind would choose fiddly M2 fixing?!

Key Features

Compact Qwiic Hubwith five Qwiic connectors (1 in, 4 out)

Qwiic pins broken out to padsfor interfacing with non-Qwiic devices

Onboard LEDfor visual power/connection status (makes it pretty too!)

Cuttable trace to disable LED because some makers like to work in the dark

Underside solder pads for easy wire soldering and re-work on the pads

M2.5 mounting holesforfiddly-freemounting

ENIG (Gold) PCB platingfor oxidation resistance and durability

4-pin 2.54mm male header stripincluded!
