GeeekPiDual FPC PCIe HAT for Raspberry Pi 5, B12 HAT 1 to 2 PCIe Interface with 40Pin GPIO Pin Header for Raspberry Pi 5

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

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

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.

I have tried using this PCIe Switch HAT with two PCIe HATs on a Raspberry Pi 5 with 8GB RAM.Neither HAT works with this Switch HAT. My Raspberry Pi 5 can not see either HAT through the switch. The cabling is correct. My Pi 5 sees all four "ports" on the switch but no HATs connected through it work. Each of the HATs I am trying to use works perfectly without the PCIe switch.
