I got one of the batch of OpenWRT One units missing the SMT standoff at the M.2 2230 spot.
No biggie; I can solder it in myself. I am glad that the mfg. included the un-attached SMT standoff because it is a pain to figure out which one to buy and also to buy just one rather than some minimum order quantity.
That said, I don’t particularly want to solder it in, because doing so would make it impossible to install double-sided 2242 SSDs.
Anyway, I did some research, and someone named Poinkachu over at the linustechtips forum mentioned rubber, tool-less inserts made by Delock, part number 18305. They simply push down through the un-threaded hole in the PCB and secure the 2230 SSD that way. It’s a good non-destructive, reversible option for those of us with this issue. Problem is that the smallest quantity I have seen them in is 10 units in a bag.
Personally, I will probably take the included SMT standoff and find a standoff of the same dimensions and super-glue it in using a dab of thick gel cyanoacrylic glue on one side, making sure the standoff touches as much of the metal on the PCB as possible to form a good ground. Using the thin liquid super-glue would cause it to wick into the surfaces via capillary action and would act as an insulator. (Obviously the Delock rubber nipple option does not care about grounding the SSD, but there is at least one ground pin in the M.2 connector.) The good thing about the super-glue option is that it is removable via acetone to dissolve the super-glue later.
Another option is to put a shallow but wide screw through the bottom of the provided SMT standoff OR a normal screw but with a wide “fender” washer. The washer can’t be too wide or it might touch other components on the board, BUT it can be a nylon washer. Its only job is mechanical fastening.
Those 2230 to 2242 extenders also work as an option, but they cost a lot more than a dab of super-glue or a M2 screw (that I already have) and nylon washer (that I can get for 50 cents at the local hardware store).
Anyway, I hope this helps you. I see the missing post as a good thing (so long as they include it in the parts bag for us to attach ourselves). It maximizes our options for SSDs. I happen to have a spare double-sided 512GB SSD that’s doing nothing; it will fit perfectly. But if I buy a 1TB or 2TB in the future, it will likely be 2230 because 2242 seems to be a rare form factor in retail SSDs (2242 seems to be most common as the OEM drive in some laptops and are often system pulls from older laptops).
