XNAS1

⚠️Important Notes

• The XNAS1 requires a 12V 10A power supply. Using other voltages may cause damage.

• The XNAS1 is designed for data storage purposes and does not currently support booting from HDD/SSD with the existing firmware.

Overview

The XNAS1 is an industrial-style NAS enclosure built on the Raspberry Pi Compute Module 5. It offers dual Ethernet (1GbE + 2.5GbE) and supports 4-bay 3.5" SATA drives for high-capacity, high-speed storage.

As a compact and flexible solution, it is fully compatible with openmediavault (OMV), enabling you to create a private cloud, share files across devices, store surveillance footage, and more - all in one reliable system.
