Specifications Overview

Helios4 is the perfect recipe of high speed interfaces to build a real NAS.

High Performance ARM System-on-Chip

The Marvell ARMADA® 388 is a robust energy-efficient System on Chip (SoC) with very powerful processing abilities especially suited for headless data processing, networking and storage. This Dual-core ARM Cortex A9 CPU clocked at 1.6 Ghz integrates a Cryptographic and XOR DMA engines to provide the best level of performance for NAS functionality.

4 x SATA 3.0 Ports

The only ARM based board on the market that offers 4x SATA 3.0 ports. This is the key feature that makes this platform the first  single board computer specially designed for Network Attached Storage. Enjoy up to 48TB of raw storage (4x Disk of 12TB) while ensuring enough throughput to share your data across your entire home or small office network.


Size: 100 mm x 100 mm

2GB DDR3L ECC Memory

A generous 2GB RAM for the most demanding applications, with ECC feature to protect your data against silent corruption.

2 x USB 3.0 Ports

Connect external storages and enjoy lighting speed to transfer data from or to your hard drives. Or connect a WiFi dongle to make Helios4 wireless.

True Gigabit ethernet

Reach the full potential of your storage over your network thanks to a full duplex Gigabit Ethernet that will always perform at maximum speed.

Ultra high speed SD card interface

Enjoy the simplicity of running your operating system directly from an SD card. Support SDHC or SDXC cards with a bus speed of up 104 MByte/s.


High performance and high density systems require adequate active cooling. Connect up to 2x PWM fans with automatic speed control and monitoring.

RICH I/O Interfaces

* Add new features with I2C and GPIO headers (LCD screen & Control buttons).
* Access serial console directly via dedicated mini USB port.

We Believe in Open Source

The Helios4 was from the start a project by community for the community.

Open source software

Because simply this project wouldn't even exist without all the amazing projects out there, any of our software contribution will of course be published on our Github.

open source hardware

We hope people will adopt our platform and make it their own therefore all hardware details along with schematics will be available on our Wiki page.
