  • 21 GPIOs in DB25 connector
  • Less than 3W power consumption
  • Power input 9-40V DC

Artila's Matrix-522 industrial box computer is a small form-factor, low-power-consumption, and Linux-ready computing platform. With a 400MHz ARM926EJ-S CPU, 64MB SDRAM, 128MB NAND Flash, and 2MB Data Flash inside, Matrix-522 ensures system high performance. Matrix-522 is equipped with multiple I/O interfaces, including two LANs, two RS232/422/485 serial ports, two CAN bus ports, two USB hosts, and 21 GPIOs. It is easy to develop pure C/C++ programs or Web-based applications (e.g. SQLite+ PHP) to run on the Matrix-522.

The CAN bus (Control Area Network) is one of the dominating communication interface for embedded control systems both in the automobile industry and the factory automation industry. The Matrix-522 comes with two isolated CAN bus 2.0 compliant ports, supporting CANSocket and CANOpen APIs.

Matrix-522 also provides a useful fail-proof design for system backup and recovery. Normally, Matrix-522 boots up from its NAND Flash. However, the Data Flash in the Matrix-522 includes a backup Linux file system as well, which will automatically boot up Matrix-522 in case the primary NAND Flash fails. If the Matrix-522 boots up from the Data Flash, a menu-driven program will appear to help you restore NAND Flash images from a USB pen drive or an SD card. Also, this program can help you save a custom image of the current file system to a USB pen drive or an SD card, so that you can easily recover the file system, or duplicate it to other Matrix-522s.

With pre-installed Linux OS, you can easily operate Matrix-522 via Telnet, or transfer files using FTP. Matrix-522 comes with a free GNU tool chain for you to develop C/C++ programs. Comprehensive examples are also available on the Matrix-522 product CD to demonstrate how to access I/O interface and hardware features. A variety of driver modules and software utilities are included on the product CD also.
