Innocard GHC38-1952 MCIO 38P PCIe 5.0 to U.2 100cm cable adapter

Purpose-built PCIe 5.0 link

This adapter connects an MCIO 38-pin host port to a U.2 drive using a 100cm cable and an included M.2-to-U.2 converter board. It targets builders who need to place NVMe storage away from the motherboard while keeping full Gen5 bandwidth. The kit suits servers or workstations where drive bays are distant from the CPU complex.

Build integration

The 100cm cable provides routing flexibility inside dense chassis, and the converter board accepts a single M.2 drive that plugs into the U.2 end. On-board 12V input protection includes a 5A fuse, 400W bidirectional TVS and a Schottky barrier rectifier. A synchronous buck converter generates 3.3V for the M.2 device with a 5.5A peak output limit and discharge control.

Sustained operation

The 3.3V rail uses a 32mΩ NexFET with reverse-current block and a hot-swap controller rated for 6.5A continuous current. Protection covers over-current, under-voltage, over/under-voltage and thermal shutdown. An SMBus EEPROM stores 64KB and level-shifts CLKREQ#, WAKE# and SMBus between 1.8V and 3.3V domains. A red LED blinks to show drive activity status.
