I’m looking for a Google Coral for my system to help with Frigate. I see most people buy the USB version, but does the PCIe version work with Frigate as well? I have PCIe 3.0 slots available on my motherboard.
Yes
All the corals work with frigate. PCIe is much faster than usb in my experience

I think you still need to install the drivers if you use the PCIe version so it just takes an extra step getting it setup.
The PCIe version requires drivers, it has the advantage of having automatic throttling and reporting the temperature.
It can be faster as well, in my case USB is 10 ms inference time while PCIe is 5 ms
I found the instructions to install the drivers but I can’t get the commands to work in the CLI. I just keep getting errors.

I’m running Hassio, am I not able to install these drivers using Hassio?
The term “hassio” has been retired for a couple of years, because it was confusing. But this is minor.
Could you help elaborate your setup / environment on your ASRock metal?
Yep, here is the info on my system

HA OS supposedly has drivers for coral installed
Thank you @tmjpugh - I was going to mention the same.
Also, @bphillips921 -
- HAOS is a locked down appliance OS - evidently (a) one cannot (easily) write something to the filesystem, and (b) I don’t think it even has
apt-get. - Wow that’s a powerful metal for HAOS.
After the Coral thing is said and done, you probably would be looking for the next resource intensive application / service to give the CPU some exercise.
Awesome! Thanks for the help @k8gg and @tmjpugh!
Yeah, I went overboard on the hardware. I have it all in a rack mount case in my basement (my setup). I couldn’t source a Coral but wanted to use Frigate so I just decided to build a new server with some power to handle Frigate until I could get a Coral. I tend to overdue things, kind of a “go big or go home” attitude.
you should of sought out one of the T series cpus,. tdp is only 35w to 65w on those things (sorry to bump I came here after searching if m.2 coral was compatible with hass os) for my overkill project 
Hi @bphillips921. I can’t see any mini-PCIe slots on your motherboard.
Did you use an adapter to go from PCIe to mini-PCIe? If so, can you link what one you used. I’m struggling to find any.
The Coral PCIe drivers don’t seem to be installed in the newly supported Odroid M1 board, I just checked with an M.2 device
Drivers aren’t in the board, it part of the OS install.
What coral model are you using?
The M.2 coral device, latest 10.0 version of hassos
There are several different models with different key types. The Odroid has an M key type slot.
As an example, If you have the dual TPU Coral, it will have the E type key and will not work.
That device wouldn’t fit the socket, how could I have installed that one?
An E Type will fit in an M slot.
