U.2 to M.2 22x110mm gender changer
This Innocard adapter converts an M.2 NVMe SSD to a U.2 SFF-8639 interface using PCIe 4.0 signalling. It is built for system integrators and technicians who need to install M.2 22110 drives into 2.5-inch U.2 drive bays or backplanes. The board is designed and manufactured in Taiwan.
Hot-plug power protection and voltage translation
An on-board PWM buck converter steps 12 V down to 3.3 V with up to 5.5 A output current and includes over-current, under-voltage and thermal shutdown safeguards. A dedicated 3.3 V hot-swap controller manages inrush current up to 6.5 A for safe drive insertion. The adapter also provides 1.8 V/3.3 V level shifting for SMBus, PERST#, CLKREQ#, WAKE# and PWRDIS signals, plus a 64 KB SMBus EEPROM and dual-status LEDs.
PCIe 4.0 and NVMe 1.3a compliance
The adapter follows the SFF-9402 Rev 1.1 pin-out and complies with the NVM Express 1.3a specification over a PCIe Gen 4 link. This single specification determines whether the host backplane and the target M.2 SSD can operate at Gen 4 speeds without signal degradation. Buyers whose platforms only support PCIe 3.0 or earlier will not gain Gen 4 performance from this part.

Questions about this item
How often will the built-in hot-plug protection IC need replacement under normal use?
The integrated hot-plug power protection IC is a solid-state component with no moving parts and does not require scheduled replacement.
What is the maximum continuous current the adapter can deliver before its protection limits activate?
The on-board 3.3 V hot-swap controller supports a maximum continuous current of 6.5 A for M.2 SSD protection.
How much heat does the PWM buck converter generate when running a 5.5 A load all day?
The synchronous buck converter includes thermal shutdown protection; under sustained load the green LED shows power ready while the red LED blinks to indicate active status.
