I want to open a door to GPUs, SATA and Google Coral and PCIe is the key. I have found a board that promises to offer this port for the pi5 and I have ordered it. I hope it works at least in some of those cases.
That's kinda on my to do list. I have a spare Pi5, a spare Pimoroni NVMe bottom board and a couple of M.2 to x4 PCIe adapter boards*. Just need to find the time...
FWIW, I've had no problems with PCIe some PCIe packet switches, PCIe SATA cards, and a VL805 based PCIe USB card. I've no reason to exspect those won't work with a Pi 5.
*: No, not PCIe to M.2. These go into an M.2 M key socket and have a standard PCIe slot on top.
Prelimary test results are in. It appears to work as expected though cards that require 12v or more than 1A @ 5v do need external power.
Only tested to the extent that a variety of carsds were recognised by lspci. Not tested with PCIe packet switches but, somewhat surprisingly, an ASM1083 PCIe to PCI bridge worked and the card on the otherside of it was correctly detected.
You do need to be caeful not to disturb the "PCIe pipe" cable when inserting/removing PCIe cards.
