PCle interface: For 5 only supports PCle x1, with Gen2 and Gen3 modes. M.2 M-key interface: supports NVMe SSD, Supports 2280/2242/2230 size SSD. (only 2280 copper pillars are welded by default). SSD booting system: Supports booting the system from the NVME SSD hard disk and storage expansion. The SSD can also be used for storage only and the system boots from TF. Dual LED: Dual LED indicators on-board: power indicator ("PWR") and M.2 activation indicator ("ACT") High-quality components: adopt high-quality electronic components and immersion gold technology, and are produced lead free. 4 M2.5 fixing holes and a concave design on the top of the board facilitate the operation and use of 40Pin GPIO. M.2 power system: The power supply circuit of the adapter board adopts a 2A current design, which is limited by the current limit of the PCIE interface of 5 (5V1A). It can provide output capability of more than 3.3V1.5A to solid state disk. Generally, the rated current marked on a solid-state disk may be 2.5A, 2.7A or even 3A, but this current corresponds to The limit value of X4 mode, and 5 only supports X1 mode, so the actual current used is higher than the rated current Much smaller, our design meets most hard drive needs. The newly designed hard disk auxiliary power supply interface on the board can 3A power supply to the hard disk. Various power supply interfaces It can be auxiliary powered from 40Pin or external power supply through the 2.54mm 2Pin interface: It can also be auxiliary powered from the USB port of 5 or an external power supply through the USB-C port or 1.254p port.
