<br />
== Technical overview ==<br />
* Four USB 2.0 ports to expand peripheral connectivity on the Raspberry Pi Zero / Zero W<br />
* Connects to the Raspberry Pi Zero via pogo pins; other Raspberry Pi models require a USB cable<br />
* Onboard USB-to-UART converter included on the board<br />
* LED indicator lights up when the USB ports are successfully enumerated<br />
* Screw standoffs use M2.5 spacing<br />
* Pogo pins support a maximum current draw of 3 A<br />
* If the Raspberry Pi Zero's USB port is configured as a wired network card, the USB hub will not be recognized<br />
* This can be fixed by adding dtoverlay=dwc2,dr_mode=host to /boot/config.txt and removing module-load=dwc2,g_ether from /boot/cmdline.txt<br />
<br />
'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
sudo nano /boot/config.txt<br />
dtoverlay=dwc2,dr_mode=host<br />
sudo nano /boot/cmdline.txt<br />
module-load=dwc2,g_ether<br />
sudo reboot<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* Exact electrical limits and compatibility depend on the specific Raspberry Pi version; verify before use<br />
* Changes to config.txt and cmdline.txt require a device reboot<br />
* If the hub is not recognized, first check the USB connector or pogo pin contacts for poor contact<br />
* Additional drivers (e.g., CP2102) may be required depending on the operating system; installation must be manually verified<br />
