1. For PCIE to M.2 SSD expansion board, supports PCle x1, supports Gen2 and Gen3 modes, supports 2242/2230/2280 specification SSD, supports booting from NVMe solid state drives and storage expansion 2. SSD can also be used for storage expansion alone, and the system is booted from a TF card; the for 5 motherboard has a built-in PCIE expansion interface, and this product is suitable for PCIE external M.2 solid-state drive expansion. 3. Support 2242/2230 size SSD 4. I support PCle x1, Gen2 and Gen3 modes 5. Onboard power indicator (PWR) and M.2SSD activity indicator (ACT) Model:PCIE to M.2 NVME Purpose:for 5th generation solid state drive expansion board Expansion board usage instructions: 1. The power circuit of the expansion board adopts a 2A current design. It is limited by the current limit of the PCle interface of the for 5 (5V1A) and can provide an output of more than 3.3V1.5A to the solid state drive. 2. Normally the rated current of an SSD can be 2.5A, 2.7A or even 3A, but these currents correspond to the limits of X4 mode 3. Since for 5 only supports X1 mode, the actual current used is much less than the rated current. Our design meets the needs of most hard drives. Note:Due to different production batches, the color of the motherboard will be different, and the appearance, color, and printing of the product will be different, which does not affect the use.
