1. Supports NVMe SSDs in 2230 or 2242 or 2280 form factors (default installation only includes 2280 standoffs). 2. Can be used for storage expansion. After the for official firmware update on May 13, 2024, it supports booting from SSD only supports PCIe 1x Gen2. Enable the NVME SSD by add following in theconfig.txtdtparam=nvme 3. The board dimensions are 56x86mm, slightly longer than the for 5. 4. Slots are provided at the 40-pin header position, ensuring no interference with cable connections. Note:Due to different product batches, the appearance , 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 5's PCIe port operates at only 1 , and after expansion, it only supports Gen2 mode, the power consumption drop to one-third of the rated parameters. For example, if an SSD is marked with 3.3V 2.5A, the current measured from the 5V side is only slightly over 500mA. In our tests, the current of two SSDs was 0.75A.
