PCIe 3.0 FPC Interface
The Radxa Cubie A7Z features an onboard PCIe 3.0 FPC interface, supporting the PCIe 3.0 standard with a single-lane (x1) high-speed data expansion interface.
You can connect a PCIe to M.2 M Key HAT via the PCIe 3.0 FPC interface and use it with an M.2 NVMe SSD to expand storage capacity.
For the specific location of the PCIe 3.0 FPC interface, please refer to the interface description section in the Hardware Interface tutorial!
Usage Guide
Currently, NVMe SSDs can only be used as expanded storage. Full functionality is under development!
To use an M.2 NVMe SSD, you need to connect it to the Cubie A7Z's FPC interface using a PCIe to M.2 M Key HAT.
- Expanding Storage
Install the PCIe to M.2 M Key HAT expansion board onto the Cubie A7Z, then install the NVMe SSD into the M.2 M Key slot on the expansion board.
After installation, use the lsblk command to verify if the NVMe SSD is recognized.
