GeeekPi Quad FPC PCIe HAT for Raspberry Pi 5, B14 HAT 1 to 4 PCIe Interface with 40Pin GPIO Pin Header for Raspberry Pi 5

Fragiles mais fonctionne bien

worked perfectly. but don’t daisy chain multiple pcie splitters. it will stop functioning

Do's what it do's just fine.

I needed to split the RasPi5 PCE1 into two channels. The Dual FPC Hat gave me a way to insert a PCIe switch into the path and let the OS (Ubuntu) take over from there. I added another PCIe hat with a WiFi7 Intel chip and was able to use lspci -v to verify everything was working as anticipated. I'm waiting for a 2 slot NVMe hat to arrive in a few days to complete the build. GeekPi is one of my goto sites and they have not let me down so far. Based on their service and the quality of parts I've received, I give them the ceremonious 5 star rating. Good job GeekPi Pete

This is a decent dual PCIe HAT for Raspberry Pi 5 that seems well-constructed and works as expected without issues. It provides 2 PCIe interfaces which are exactly what I needed although initially I was contemplating whether to get the dual or quad version. It comes with everything I need (2x 8.5x40/8.5x60 mm FFC cables and screws/standoffs) and the installation and setup is no more complicated than any other although certain amount of patience might be required at times when dealing with the FFC cables. Note that this uses ASM1182e chip and depending upon your specific setup, you might need to update the firmware in order for the NVMe SSD to boot since they are sitting behind a PCIe packet switch. Also keep in mind that the way packet switching works is like a splitter of sorts. As such, available bandwidth is equally divided between 2 the PCIe devices if they were to be accessed simultaneously. ≡ Value All things considered, this is a decent dual PCIe HAT for Raspberry Pi 5 that's well-constructed and works as expected without issues. It's reasonably priced at $32 for what it provides and its overall build quality, usability, versatility, and performance.
