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

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

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

had one PCIE slot that was bad, but otherwise worked.

Good item, could do with faster switching between devices connected, otherwise it does what is described

It’s your typical raspberry pi hat. It slides on the GOIO pins easily, height adjustment is quick and easy, the ribbon cables are a good usable length, price is not bad for what it does.

This will give me two PCIe devices. One will be an NVME SSD 1TB boot and the other will allow 4 SATA drives, might replace the stock power supply to support 4 SATA drives. Thank You for a great product.

Really fast access

I wasn't sure if I connected it properly, because it didn't show signs of life until I plugged in an nvme card rated at 7200 MB/s. It's running at 425.89 MB/s
