4. Installation and compatibility checklist
Confirm the motherboard has an M.2 2280 B+M-key slot wired for PCIe.
Verify that the slot supplies 3.3 V and supports the required PCIe connection.
Do not assume every M.2 slot supports this module; some slots provide SATA only.
Provide suitable cooling, particularly for sustained inference workloads.
Install the Coral PCIe driver and Edge TPU runtime.
