The Story
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 toĀ solderĀ theĀ included 4-pin headerĀ to the board and use it as a breadboard adapter for Qwiic devices -Ā handy!
I2C and Qwiic devices use four lines for power and communication -Ā GND, 3.3V, SDAĀ andĀ SCL. 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 youāre not into that blinky life, you can cut the highlighted trace to disable it.
We also usedĀ M2.5 mounting holesĀ as they're a popular size with easy-to-sourceĀ fixings...because who in their right mind would choose fiddly M2 fixing?!
Key Features
š¤ Compact Qwiic HubĀ with five Qwiic connectors (1 in, 4 out)
šĀ Qwiic pins broken out to padsĀ for interfacing with non-Qwiic devices
š” Onboard LEDĀ for visual power/connection status (makes it pretty too!)
šŖĀ Cuttable trace to disable LED because some makers like to work in the dark
ā©ļøĀ Underside solder pads for easy wire soldering and re-work on the pads
š©Ā M2.5 mounting holesĀ forĀ fiddly-freeĀ mounting
šŖĀ ENIG (Gold) PCB platingĀ for oxidation resistance and durability
šøĀ 4-pin 2.54mm male header stripĀ included!
