<br />
== Technical overview ==<br />
* The module provides four USB expansion ports (USB1–USB4) for connecting external USB devices.<br />
* An integrated USB-to-UART port enables a serial connection to a PC.<br />
* Communication uses a CP2102 controller board; the corresponding driver must be installed on the PC.<br />
* A switch on the rear edge of the module selects or enables the Raspberry Pi's serial port.<br />
* Two micro-USB connectors are present; only the connector labeled 'USB HUB' is used for USB expansion, not the 'USB to UART' connector.<br />
<br />
'''Commands and examples – verify before use:''' <br />

<br />
== Notes and version constraints ==<br />
* If serial connection fails, enable the serial console option using 'sudo raspi-config'.<br />
* If the Raspberry Pi Zero's USB port is configured as a wired network card, the USB HUB may not be recognized.<br />
* For models such as Raspberry Pi B+/2B/3B, a USB cable is required because the module cannot be attached directly via the micro-USB connector.<br />
* Ensure the USB HUB connector is properly connected to the Raspberry Pi's USB port to avoid recognition issues.<br />
