Where to buy components (in US) to build SPI cable for Up Squared?

I'm interested in flashing a new BIOS to the Up Squared directly, using the CN22 header.

I know there's https://wiki.up-community.org/BIOS_chip_flashing_on_UP_Squared which explains what cable is needed, but I'm having trouble finding components to create it.
I've looked on mouser, digikey etc., but can't find a 12-pin 0.635mm (0.025") socket, or jumper wire with 0.635mm pitch. I was wondering if anyone could help?

    From Mouser.com:

    • 1 of Samtec FFSD-06-D-06.00-01-N (cut off the end that doesn't have PIN 1 where you want it)
    • 1 of Samtec ISDM-05-K (ISDM-07-K header should work as well)
    • 10 of Samtec CC83L-2426-L (7 plus 3 spares)

    I also needed a ADP-SF600-TO-SF100xCB adapter for my flash programmer.

    One will probably also need some jewler's glasses and some needle-nose pliers.

    It took me about three hours to make the cable, having never done it before.
