This item is for extending the motherboard's M.2 NGFF slot out of the SATA 7PIN connector. This adapter card simply connects the signal from the M.2 KEY BM connector to the SATA 7PIN connector, so the adapter card does NOT need to be driven. If you do not recognize the interface, please check whether it is SATA KEY-B signal. This board supports motherboard size 2242 2260 2280. The default is 2280. If you want to use other sizes, just cut it along the V-CUT line in the middle of the PCB. Extend the M.2 KEY BM slot on the motherboard out of the SATA 7PIN connector.
