Frequently Asked Questions

Does the Argon ONE M.2 SATA Expansion Board work with NVMe SSDs?

No. It supports M.2 SATA SSDs with B-Key or B+M Key connectors. M-key-only NVMe drives are not listed as compatible.

Which SSD sizes fit in the Argon ONE M.2 board?

M.2 SATA SSDs in 2230, 2242, 2260 and 2280 form factors are supported, as long as they use a B-Key or B+M Key connector.

Will this board fit my original Argon ONE case or a different Pi case?

It is designed for the Argon ONE V2 case and replaces that case's bottom panel. The listing does not claim compatibility with other cases, and the Argon ONE V2 case is sold separately.

How does the SSD connect to the Raspberry Pi 4?

Through the included USB 3.0 bridge adapter, which plugs into one of the Pi 4's USB 3.0 ports. UASP support helps get the most transfer speed out of that USB 3.0 connection.

What comes in the box, and is an SSD included?

The kit includes the M.2 SATA expansion board, a USB 3.0 bridge adapter, a bottom cover plate, screws, rubber feet and an installation guide. The SSD is not included, and neither is the Argon ONE V2 case. Check the product listing for current warranty terms.
