PCIe 4.0 U.2 to M.2 22x110mm adapter
This adapter converts a U.2 SFF-8639 port to an M.2 NVMe slot for 22x110mm drives. It implements PCIe Gen 4 signalling and includes a synchronous buck converter that steps 12 V down to 3.3 V with up to 5.5 A output current. Multiple protection circuits and a hot-swap controller guard the connected SSD. LEDs show power-ready and drive-activity status.
Builders adding NVMe storage via a U.2 bay
The card suits integrators who need to install a 22x110mm M.2 NVMe drive into an existing U.2 backplane or enclosure. It handles 3.3 V and 1.8 V sideband switching for PERST#, CLKREQ# and WAKE# signals. Builders requiring a different M.2 form factor or a direct PCIe slot connection should look at other adapter types.
PCIe Gen 4 support with 5.5 A 3.3 V power delivery
The single specification that determines fit is the PCIe Gen 4 rating combined with the on-board converter’s 5.5 A maximum output at 3.3 V. Drives whose power draw exceeds this limit or that need a different keying will not work correctly with this adapter.

Questions about this item
Does this adapter need a 12V power source to run the onboard PWM buck converter for the M.2 SSD?
Yes, the built-in PWM converter steps 12V down to 3.3V and can deliver up to 5.5A to the M.2 NVMe drive.
Which M.2 keying and length does the 22x110mm slot accept, and how is the drive secured?
The slot takes a 22mm wide, 110mm long M-key NVMe SSD; the drive is held by the standard M.2 mounting screw on the host board.
What does the red LED blinking indicate, and when should the EEPROM be reprogrammed?
The red LED blinks when the SSD is active; the 64KB SMBUS EEPROM stores configuration data and only needs reprogramming if the drive identity changes.
