The 52Pi P02 is an expansion board for the Raspberry Pi 5 that converts the Pi’s PCIe into a PCIe x1 slot. The board gets connected to the bottom of the Pi and taps into the Pi’s power with the help of onboard pogo pins. It supports PCIe Gen2/Gen3 speeds and features a JST connector for external power input.
While writing about the 52Pi NVdigi Expansion Board, I found the P02 PCIe expansion board for Raspberry Pi 5 interesting. It features a PCIe x1 slot, allowing you to install various off-the-shelf accessories like network cards, USB expansions, and more. You can even use a PCIe riser to connect a GPU with standard PC products. This isn’t the only 52Pi product we’ve covered; we’ve also looked at the 52Pi water cooling kit and the 52Pi CM4 Router Board. Feel free to check those out if you’re interested in the topic.
52Pi P02 PCIe Expansion Board Specification:
- Compatibility – Made for Raspberry Pi 5.
- Open slot design – Works with PCIe cards (x1, x2, x4, x8, x16).
- PCIe x1 support – Compatible with Gen2 and Gen3 PCIe x1 interfaces.
- Integrated Power Supply – 12V power supply supporting up to 1A, plus an external 12V input.
- PCIe Ultra-short Signal Lines – Uses short paths for PCIe for stable and fast communication, meeting PCIe 3.0 standard requirements.
- Power Outputs – +12V/1A and +3.3V/3A to the PCIe x1 slot.
- Dimensions – 85x80mm.
The company says this board is good for anyone wanting to get more out of their Raspberry Pi. In simple terms, if you’re looking to add a large GPU, fast 10GbE networking, or turn your Pi into a home server, this little board will be very helpful. The company also provides a wiki page with further hardware details and instructions on how to enable PCIe x1 on the Pi, the company also provides assembly instructions on the same page.
Inside the box, you’ll find one P02 PCIe slot specifically designed for the Raspberry Pi 5, one custom PCIe FFC cable for connections, four M2.5 x 6mm coupler pillars for mounting, eight M2.5 x 4mm flat head screws for assembly, M2.5 screwdriver for installation. This kit provides everything needed to set up and start using the expansion board with your Raspberry Pi 5.
The 52Pi P02 PCIe expansion board is priced at $24.99 and it’s available for pre-sale on the 52Pi online store.
