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

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 GeekPiPete

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.

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

I wanted to put this under an m.2 ssd hat, but it will not boot from the nvme. am keeping it, but is is meh

Really fast access

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.

This item was received for free, however, this review is 100% honest and unbiased.Great expansion board for my RPI 5, looks and feels high quality, and the packaging arrived a bit... flat but no damage to the board or any components so, not the seller's fault really.It came with Qty 4 FPCs, screws posts, and even a screw driver, my installation was easy, just make sure the Pi connector is facing the correct way, also the pi connector is a flip-style one compared to the HAT 1,2,3,4 are pull. I'm only using a single PCIe hat on my RPI5 but likely will be getting a second one since it made it so easy to stack'em

I broke 2 of the pcie connectors trying to install a ribbon in them. Need to use the trap door connectors up underneath. It is not impossible, but a PITA to add hat #3 without disassembling the rest st.
