Qwiic USB Hub - USB2514B
There are times when you have multiple USB devices in your prototype or device and you just want to plug in one cable. You need a built in USB hub!
The Qwiic USB Hub is a simple breakout board for the USB2514B USB hub IC. What gives it extra flair is the ability to configure the device over I2C. Out of the box, the board will appear as a standard USB 2.0 Hub; no configuration necessary. Closing the I2C jumper will put the device into configuration mode. We've got an Arduino Library to help you set the various parameters of the hub including VID/PID, downstream max current, even language ID and product names.
Known Issues: The power control MOSFETs on this version (x02) are not functional. While each port is on by default, they cannot be turned off in software.
Note: Once the configuration bytes are set and the USB2514B is told to 'attach' it will enumerate as a HUB and the configuration cannot be changed until the IC is reset.
Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.
