Is this the M.2 version? or do I have to purchase the expansion board separately

Hi Jirayu,


This is just the case, the expansion boards will be available soon hopefully!

I just received the V3 thinking it had the M.2 expansion.
Will I be able to upgrade with a new backplate?

Hi Graeme,

Yes, you can use the same M.2 SATA backplate with the Argon One v3 as the previous Argon One cases, the descriptions and product info needs updates. Please note that it is designed for SATA SSDs though such as our SATA WD Green and Blue variants.

If you want to use NVMe SSDs you’ll need to wait for the new backplate to become available.

thanks Bryce,

I think I’ll wait for the NVME PCIe expansion backplate.


Any Idea when NVME PCIe backplate will be available?

Hi Geoff,

It looks like the NVMe expansions plate (SKU: CE09857) should be back in stock on our website soon after the 20th of march. If you haven’t already seen it there is a link on the product page to sign up to get notified when this product is back in stock.

We use that notification to let you know as soon as we get stock of the product again.

Hope this information helps!

Thanks Sam, very helpful indeed :slight_smile:

Which audio jack SKU should I order for the Argon ONE V3 case?

" OPTIONAL 3.5mm audio jack via the internal DAC audio board upgrade (see separate listing)"


Hi @Glen83734, Welcome to the Forums!!!

The DAC upgrade for the cases requires the Argon BLSTR DAC.

I’ll look at getting a link added to the description of the case so it’s easier to find.

I bought this case and the Argon ONE V3 M.2 NVMe PCIe expansion board. Core Electronics didn’t have any SSDs in stock at the time so I purchased an MSI Spatium M450 PCIe 4.0 drive from another vendor. Now I can’t get the Pi to detect the SSD and I’m wondering if it’s not even detecting the expansion board???

I can see the PCI bridge with lspci but I can’t see a storage controller or the actual storage:

$ sudo lspci -nnvmm
Slot:	00:00.0
Class:	PCI bridge [0604]
Vendor:	Broadcom Inc. and subsidiaries [14e4]
Device:	BCM2712 PCIe Bridge [2712]
Rev:	21
ProgIf:	00

Slot:	01:00.0
Class:	Ethernet controller [0200]
Vendor:	Raspberry Pi Ltd [1de4]
Device:	RP1 PCIe 2.0 South Bridge [0001]
ProgIf:	00

With lsblk I can only see the SSD card I’m booting from:

$ sudo lsblk
mmcblk0     179:0    0 57.5G  0 disk 
├─mmcblk0p1 179:1    0  512M  0 part /boot/firmware
└─mmcblk0p2 179:2    0   57G  0 part /

I’ve tried reseating the PCIe ribbon cable and even swapped it out for the other one that came with the expansion board. The ribbon is going as far in as it physically can and I’m pretty sure I’ve got the copper side facing the right way according to the instructions in the booklet…

Am I doing something wrong? Any suggestions on next troubleshooting steps would be welcome :slight_smile:

Hi @Matthew274843,

Thanks for sharing this information.

I’m wondering if this is a case of the NVMe controller on the Drive not being compatible with the Pi 5. I wasn’t able to find anyone else who has that drive working on the Pi 5 either.
A good resource is this user test site

Are you getting any error messages related to PCIe or NVMe when you run dmesg?

I’m so embarrassed :flushed:

The SSD wasn’t seated correctly :man_facepalming: It’s working fine now!

I’ll have to run a speed test and add that SSD to the list of compatible devices.
