X1509

Overview

1. This X1509 board supports 8 SATA ports, delivering a high-speed and high-capacity storage solution for Raspberry Pi CM5. It reaches a total storage capacity of up to 176TB (22TB per single drive).

2. Designed with a compact form factor, it is equipped with multiple ports and versatile peripherals for extensive expansion.

3. Built-in high-efficiency DC/DC step-down converters provide a stable 5V 12A output. A single power supply is sufficient to power both the CM5 module and all connected SATA storage devices.

Ideal for building home media centers, personal NAS systems and CCTV video storage servers.

Dual HDMI 2.0 Ports Supports dual 4K display output for multimedia playback and industrial applications. Dual MIPI DSI/CSI-2 Connectors 22-pin FPC connectors (0.5mm pitch), fully compatible with Raspberry Pi 5 CSI and DSI modules for seamless camera and display connection. 12-Pin GPIO Header Integrates general I/O ports, external power button and 12V PWM fan header, enabling DIY customization for enclosures and cooling systems. MicroSD Card Slot Works with Compute Module 5 Lite variants (models without onboard eMMC storage). USB Connectors USB-C: Dedicated for OS image loading on CM5 models with onboard eMMC. USB2.0 Type-A & USB3.0 Type-A: For connecting external devices such as USB flash drives, keyboards and mice. PWM Fan Connector Used for active heat dissipation. RTC Battery Connector Keeps the system clock accurate even when the device is powered off. Power Button Controls power-on and power-off for both CM5 and connected SATA devices.
Built-in LED Indicators	HDD/SSD Status LED Flashing: Data reading / writing Solid On: Drive connected normally Off: No drive detected Power Indicator: Red LED Activity Indicator: Green LED
Power Supply & Control	Built-in High-efficiency DC/DC Step-down Converters Deliver stable 5V 12A output. One single power supply can power the CM5 module and all attached SATA drives simultaneously. Automatic Drive Power Cut-off Automatically cuts power to SATA devices when CM5 shuts down. This function only works with DC power input; it is not supported via the 4-pin ATX connector.
Dual Power Input	Input Voltage: 12V DC ± 5% Warning: Over-voltage will permanently damage your hard drives! Recommended power supply for DC jack: For 8 × 2.5" SATA HDD/SSD: 12V 10A power adapter For 4 × 3.5" SATA HDD: 12V 10A power adapter Recommended power supply for 4-pin ATX connector: 12V 20A Warning: Only one power source shall be connected at a time.
Notes	The X1509 does not support system boot from SATA drives under the current CM5 firmware version.
