Technical overview
- The module provides four USB expansion ports (USB1–USB4) for connecting external USB devices.
- An integrated USB-to-UART port enables a serial connection to a PC.
- Communication uses a CP2102 controller board; the corresponding driver must be installed on the PC.
- A switch on the rear edge of the module selects or enables the Raspberry Pi's serial port.
- Two micro-USB connectors are present; only the connector labeled 'USB HUB' is used for USB expansion, not the 'USB to UART' connector.
Commands and examples – verify before use:
sudo raspi-config
Notes and version constraints
- If serial connection fails, enable the serial console option using 'sudo raspi-config'.
- If the Raspberry Pi Zero's USB port is configured as a wired network card, the USB HUB may not be recognized.
- 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.
- Ensure the USB HUB connector is properly connected to the Raspberry Pi's USB port to avoid recognition issues.
