6. Maintenance
To ensure optimal performance and longevity of your Waveshare PCIe to 4-Ch USB 3.2 Gen1 Board (C), keep it in a clean, dry environment. Avoid exposing the board to extreme temperatures, humidity, or direct sunlight. Regularly check connections to ensure they are secure. Disconnect power before cleaning or making any physical adjustments.
7. Troubleshooting
- Device not recognized: Ensure the PCIe cable is correctly and securely connected to both the Waveshare board and the Raspberry Pi 5. Verify that the board is receiving adequate power through one of the supported methods.
- Slow transmission speed: While the board supports up to 5Gbps, actual speeds may vary depending on the connected device, cable quality, and overall system load. Ensure you are using USB 3.2 Gen1 compatible devices and cables for optimal performance.
- Power issues with connected devices: If a connected USB device is not receiving enough power, ensure the power supply to the Waveshare board is sufficient. Utilize the independent power control feature to manage power distribution if necessary.
- Board not fitting in case: Ensure any heat sinks on your Raspberry Pi 5 are low-profile to allow for proper clearance with the mounting plate and case.
