This showed that the Raspberry Pi would happily talk with a VL805-based USB 3.0 PCIe expansion card, as well as a Realtek RTL8111-based Ethernet card, but not a number of other PCIe cards.

Unfortunately it’s not quite as simple as just soldering on a four-wire USB cable. The modem relies on the 3.3V power from the Mini PCI-e slot instead of the 5V from USB. No problem ...

A PCIe expansion card uses your extra PCIe sockets ... kind of USB port like a USB-c or if you want to add more USB 3.0 ports to your PC. Are you always running out of space?

A drop-in replacement for the VL805 USB controller IC that bridges the PCIe bus signals to the USB 3.0 connector on the Raspberry Pi 4. A hot air rework station is required for the removal of the ...
