Supprots PCle: For Raspberry Pi 5 only supports PCle x1, with Gen2 and Gen3 modes M.2 M-key, 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 supply, The power supply circuit of the expansion board adopts a 2A current design, which is limited by the current limit of the PCIE interface of for Raspberry Pi 5 (5V1A), and can provide 3.3V over 15A to the SSD, Generally, the current requirements marked on SSD may be 2.5A, 2.7A or even 3A but this current corresponds to the max value of PCle x4 mode, however, for Raspberry Pi 5 only supports x1 mode, so the actual current needed is much smaller. Our designs meet most SSD needs. (ln addition, our company has a version with auxiliary power supply, which can power the SSD with 3A or 5A).
