MCDODO

MCDODO P02 PCIe x1 Expansion Board for Raspberry Pi 5

SKU CH-E8TM-H1CGG

Adds a PCIe x1 slot to Raspberry Pi 5 for network cards and other expansion boards

  • Product typeSingle Board Computers
  • Adds a PCIe x1 slot to Raspberry Pi 5
  • Open slot accepts x1, x2, x4, x8, x16 cards
  • Works with PCIe Gen2 and Gen3 speeds
  • Supports network interface cards for wired connectivity
  • Includes FPC cable, screws and screwdriver

Pi 5 PCIe x1 expansion

The MCDODO P02 board adds a PCIe x1 slot to a Raspberry Pi 5 using the native PCIe FPC connector. It targets makers who need a single add-in card such as a network interface without redesigning their carrier board.

Replaces HAT-only networking

Builders who previously relied on USB or GPIO bit-banged Ethernet can now install a native PCIe network card. The upgrade is worth it when the project demands lower latency or higher throughput than the USB bus can deliver.

Sustained Gen2 or Gen3 link

The open-ended slot accepts x1, x2, x4, x8 or x16 cards while negotiating a x1 link at either Gen2 or Gen3 speeds. Under continuous traffic the connection remains stable because the FPC cable and mounting screws keep the signal path mechanically secure.

Questions about this item

What physical space does the open slot design of the MCDODO P02 require for a PCIe x1 network card?

The open slot design structurally accepts x1, x2, x4, x8 and x16 cards, so a PCIe x1 network card fits without a closed-end bracket.

How do I install the FPC cable and screw pack on the Raspberry Pi 5, and what step is often missed?

Connect the FPC cable to the Pi 5 PCIe connector, secure the board with the screw pack and screwdriver, then enable the PCIe interface in the Pi 5 boot configuration.

When will the FPC cable or screw pack need replacement on the MCDODO P02?

Replace the FPC cable if the flex ribbon shows creases or broken traces, and replace screws if threads strip during repeated mounting.
