Figure 5: The PCIe HAT mounted on a Raspberry Pi 5. Mounting the HAT
Align the HAT with the Raspberry Pi 5's GPIO pins and mounting holes. Use the provided standoffs and screws to secure the HAT firmly to the Raspberry Pi 5 board. Ensure the 2*20 pin header is correctly aligned and inserted into the Raspberry Pi's GPIO header.
4. Betjeningsvejledning
The Waveshare 4-Ch PCIe FFC Adapter expands the PCIe capabilities of your Raspberry Pi 5. Once physically installed, the Raspberry Pi's operating system (e.g., Raspberry Pi OS) should detect the PCIe interface.
Connecting PCIe Devices
The HAT provides four FFC connectors (PCIe1, PCIe2, PCIe3, PCIe4) for connecting external PCIe devices. Use appropriate FFC cables to connect your desired PCIe peripherals (e.g., NVMe SSDs, network cards, AI accelerators) to these connectors.
PCIe Gen2 Performance
The adapter supports PCIe Gen2 transmission speeds, offering a data rate of up to 5 Gbps per lane. Ensure your connected PCIe devices are compatible with PCIe Gen2 for optimal performance.
Software konfiguration
Depending on the PCIe device connected, additional software drivers or kernel modules may be required. Refer to the documentation for your specific PCIe peripheral and the Raspberry Pi OS for necessary configuration steps.

5. Vedligeholdelse
To ensure the longevity and optimal performance of your Waveshare 4-Ch PCIe FFC Adapter:
- Hold printpladen ren og fri for støv og snavs. Brug en blød, tør børste eller trykluft til rengøring.
- Undgå at udsætte boardet for ekstreme temperaturer, fugtighed eller direkte sollys.
- Hold fast i kanterne på kortet for at forhindre beskadigelse af komponenter eller statisk elektricitet.
- Ensure all FFC cables are securely connected and not bent sharply, which could damage the conductors.
6. Fejlfinding
If you encounter issues with your PCIe FFC Adapter, consider the following troubleshooting steps:
- Enhed ikke fundet:
- Verify that the FFC cable connecting the HAT to the Raspberry Pi 5 is correctly and securely seated at both ends.
- Ensure the PCIe peripheral device is properly connected to one of the HAT's FFC connectors.
- Check the Raspberry Pi 5's operating system for PCIe device detection using commands like
lspci. - Confirm that the Raspberry Pi 5's firmware and OS are up to date.
- Ydelsesproblemer:
- Ensure your PCIe peripheral is compatible with PCIe Gen2 speeds.
- Check for any power supply limitations if multiple high-power PCIe devices are connected.
- Fysisk skade:
- Inspect the FFC cables for any kinks, tears, or damage.
- Examine the HAT and Raspberry Pi 5 for any visible damage to connectors or components.
