This is a bracket I designed to allow the SI-PEX4004 SATA card to be securely mounted to the CM4IO board. The PCIe slot with the CM4IO is a bit loose and this can cause the system to crash if the card is wobbled. With this bracket, I have been running the cm4 with this card for months. Use any 2 random screws which fit the holes. I made them extra long so you can use any screw.
