U.3 to M.2 NVMe gender changer
This Innocard adapter converts an M.2 NVMe solid-state drive to a U.3 SFF-8639 interface. It operates at PCIe Gen4 speeds of 16 GT/s. The unit is designed and manufactured in Taiwan.
Suits hot-swap bays needing power protection
Builders installing M.2 NVMe drives into U.3 backplanes with hot-swap capability will find the integrated eFuse and TVS protection useful. Systems without a U.3 connector or without hot-swap requirements cannot use this changer.
Deciding spec: 5.5 A maximum output current
The onboard PWM buck converter delivers up to 5.5 A at 3.3 V to the M.2 drive with overcurrent, undervoltage and thermal safeguards. If the target SSD draws more than this limit, the adapter will shut down.

Questions about this item
What PCIe generation does this U.3 to M.2 adapter support and what is the maximum data rate?
This adapter supports PCIe Gen4 with a maximum data rate of 16GT/s.
What physical connector standard and pin-out specification does the U.3 side of this adapter use?
The U.3 side uses an SFF-8639 connector with a 30u” gold plating and a pin-out defined by the SFF-9402 Rev1.1 specification.
How is the M.2 NVMe SSD powered on this adapter and what protection does the hot-swap circuit provide?
A PWM synchronous buck converter steps 12V down to 3.3V for the M.2 drive with a 5.5A maximum output current, while the built-in eFuse provides hot-plug protection with a programmable 6.5A current limit and inrush current slew rate control.
