Association standard M.2 M Key gold finger, high gold plating: strong oxidation resistance, good conductivity and wear resistance. Multi-layer circuit board is adopted for lossless transmission: 4-layer circuit board is adopted, which has very strong anti-interference ability, effectively ensuring the stability of PCI-E high-speed signal transmission, data integrity and impedance matching. The card slot is designed with a broken end, which is compatible with X1 X4 X8 X16 and full-scale PCI-E equipment. Adopt horizontal small 4PIN power supply interface, which can effectively avoid interference with PCI-E equipment after the power cord is inserted. Equipment indicator light: the connection is normal, the equipment is electrified, and the indicator light is on.
