Matrix-504 Data Sheet

Introduction

The Matrix-504 is Artila's 2nd-generation ARM9- based box computer with pre-built Linux kernel and file system. It comes with a 400MHz ARM9 CPU, 128MB NAND Flash and 64MB SDRAM. Which enbales the Matrix-504 perform more tasks at the same time while retaining high responsiveness.

UBI File System & Failover Mechansim

The Matrix-504 uses UBI file system for its on-board NAND Flash. The UBI file system offers better write performance and more reliable bad-block handling over JFFS2.

If the NAND Flash file system does crash for any reason, the Matrix-504 will automatically boot up from its on-board 2MB Data Flash (read only). This failover mechanism allows users to rescue the Matrix-504 in a limited Linux environment.

Support Wire and Wireless Networking

The Matrix-504 comes one standard 10/100Mbps Ethernet port for wired networking. Besides, it is easy to add IEEE-802.11b/g WiFi support by simply plugging an USB WiFi dongle into the Matrix-504.

Four High Speed TTYs (Serial Interface)

The Matrix-504 provides four high-speed TTY ports: Port 1 supports RS-232/422/485 and Port 2 to Port 4 support RS-232/485. The RS-485 interface features hardware direction control to ease communication programming.

GNU Tool Chain for App. Development

Open-source GNU Tool Chain, including C/C++ cross-compiler and POSIX standard C/C++ library, is bundled with the Matrix-504 for free.
