raspberry-pi-pcie-devices VS AgroPi

Generally yes. M.2 wifi cards are just PCI-E (except for Intel CNVio). Jeff Geerling tried a bunch of different PCI-E cards with the Raspberry Pi 4 Compute Module which does expose the PCI-E interface: https://pipci.jeffgeerling.com/

We're also trying to preserve the utility of older cards by getting at least portions of the drivers working on alternate platforms (like arm64), so they can be repurposed for Plex/Jellyfin transcoding, retro gaming, GPU compute, etc.: https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...

The current answer is maybe: https://github.com/geerlingguy/raspberry-pi-pcie-devices/iss...

The PCIe implementation on the 5 is supposedly more complete/less broken than on the CM4, but so far the only person crazy/inspired enough to test hasn't gotten back to this card with their Pi 5 setup.

Just a note that if you're _serious_ about WiFi on the Raspberry Pi... you should use an external WiFi adapter—either PCIe or USB.

With the Compute Module 4, I've successfully tested a variety of adapters [1], from WiFi 6E to older mini PCIe and M.2 cards. There's even a board made for the purpose of multi-WiFi testing, the Seaberry [2].

The Raspberry Pi 5 works with all the PCIe WiFi chips I've tested (haven't had time to summarize testing on pipci database site yet, including a mt7921u-based WiFi 6E USB adapter (haven't written that up, but check out [3]).

https://pipci.jeffgeerling.com honestly I'd get a home server and run HA through docker, it's gotten me into home servers.

The simplest access you can get would be by using a CM board (as that has PCI Express available on its connectors) but driver issues galore exist. AMD have been more open the the "greenies" but the closest result I have seen is documented by Jeff Geerling

Are you familiar with a YouTuber named Jeff Geerling? He does some pretty far out stuff with pi’s like connecting video cards to them, etc. here’s a videoabout stuff you could do, I haven’t watched it myself. He’s got this website that has a list of accessories he’s tried with the pi. While I was looking for his channel I saw a ton of videos on YouTube for stuff to do with the pi. Curious to see what you end up doing… I guess I’m kinda hoping you do something that utilizes the full potential of the 4 😁

As a part of my engineering masters degree me & my buddies decided to develop a controlled environmental chamber of sorts to help people to learn how to grow plants and mushrooms. We are at the stage of implementing actuation, which is essentially controlling a set of 4 relays, so you will be able to hookup anything you like. Currently we are using 3 sensors, ambient light sensor, temperature and humidity sensor and gas sensor for tvoc and eco2 measurements.
