PCle interface, for 5 only supports PCle x1 and Gen2 and Gen3 modes M.2 M-key interfaces, supporting NVMe solid-state drives Support 2242/2230 size SSDs (default only welding 2242 copper columns) SSD boot system, Support booting the system from NVME SSD hard drive and storage expansion. SSD can also be used only for storage expansion and the system can be booted from TF M.2 Power supply system, The power circuit of the adapter board adopts a 2A current design, which is limited by the current limit of the for 5's PCIE interface (5V1A). The adapter board can provide an output capacity of 3.3V 15A or above for solid-state drives. The rated current indicated on a typical solid-state drive may be 2. A or even 3A, but this current corresponds to the limit value of X4 mode, while the for 5 only supports X1 mode, so the actual current used is much smaller than the rated current. Our design meets most hard drive requirements Dual LED indicator lights, On board power indicator light ("PWR") and M.2 hard drive operation indicator light ("ACT") Colour:As Shown Material:PCB+aluminum alloy Package Contents: 1 * adapter board 1 * FPC line 4 * copper pillars 1 * aluminum alloy shell with accessories 1 * heat sink with accessories Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
