	X1509 V1.1		ACTIVE	hardware		software

Product Overview

The X1509 is a purpose-built carrier board for the Raspberry Pi CM5, combining dual Ethernet (1GbE + 2.5GbE), 8 SATA ports, and versatile peripherals in a compact form factor. It delivers premium high-capacity, high-speed storage upgrades for your CM5.

It comes with dual 12V power input options: a regular DC jack and a 4-pin ATX power connector. Built-in load switches fully power off SATA devices when the system shuts down, while high-efficiency step-down converters offer stable 5V 12A output. One single power supply can easily run your CM5 and all connected SATA storage devices.

Whether you need a home media center, personal NAS or CCTV video storage, this expansion card is an ideal choice. It lets you securely store your multimedia files and stream content locally or remotely with outstanding performance.
