1. Supports NVMe SSDs in 2230/2242/2280 form factors (default installation only includes 2280 standoffs). 2. Can be used for storage expansion. After the for Raspberry Pi official firmware update on May 13, 2024, it supports booting from SSD; only supports PCIe 1x Gen2. Enable the NVME SSD by add following command in theconfig.txtdtparam=nvme 3. The board dimensions are 56x86mm, slightly longer than the for Raspberry Pi 5. 4. Slots are provided at the 40-pin header position, ensuring no interference with DuPont cable connections. Note:Due to different product batches, the appearance may vary, which does not affect the use. Reserves a 2-pin header with a 2.54mm pitch. If there are concerns about insufficient power supply, an external auxiliary power source can be connected through this interface. In practice, since the for Raspberry Pi 5's PCIe port operates at only 1 lane, and after expansion, it only supports Gen2 mode, the power consumption will drop to one-third of the rated parameters. For example, if an SSD is marked with 3.3V 2.5A, the peak current measured from the 5V side is only slightly over 500mA. In our tests, the peak current of two SSDs was 0.75A.
