AT91SAM9G20 Linux Box: 8x RS232/422/485, 2x LAN, 2x USB, Audio US$690.00

AT91SAM9G20 Linux Box: 8x RS232/422/485, 2x LAN, 2x USB, Audio

ARM926EJ-S Industrial Linux Box Computer

  • Atmel 400MHz ARM9 processor (AT91SAM9G20)
  • Linux kernel 2.6.29 with file system
  • 64MB SDRAM, 128MB NAND Flash
  • Two 10/100M Ethernet ports
  • Eight RS-232/422/485 serial ports
  • 2x USB Host
  • 21x General Purpose IOs (GPIO)
  • 1x Audio out
  • Less than 3W power consumption

Artila’s Matrix-518 industrial box computer is a small form-factor, low power consumption, and Linux-ready computing platform. With a 400MHz ARM9 CPU, 64MB SDRAM, and 128MB NAND Flash inside, Matrix-518 ensures system high performance. Matrix-518 is equipped with multiple I/O interfaces, including 2x Ethernet, 8 x RS-232/422/485 serial ports, 2 x USB hosts, 21 x GPIOs, and 1 audio out. It is easy to develop pure C/C++ programs or Web-based applications (ex: SQLite+ PHP) to run on top of the Matrix-518.

Matrix-518 is a reliable embedded computer to be used as a unattended controller 24/7 non-stop. It is ideal for all kinds of industrial applications, including intelligent transportation system (ITS), building automation, energy-saving system, scenario control systems, and factory automation. Matrix-518 also provides a useful fail-proof design for system backup and recovery. Normally, Matrix-518 boots up from its NAND Flash. However, the Data Flash in Matrix-518 includes a backup Linux file system as well, which will automatically boot up Matrix-518 in case the primary NAND Flash fails. If the Matrix-518 boots up from the Data Flash, a menu-driven program will appear to help users restore NAND Flash images from a USB pen drive or an SD card. Also, this program can help users make an custom image of the current file system to a USB pen drive or an SD card, so that users can easily recover the file system, or duplicate it to other Matrix-518s. Please refer to the user guide for more detailed information.

ARM926EJ-S Linux Box System Architecture

With pre-installed Linux OS, users can easily operate Matrix-518 via Telnet, or transfer files using FTP.

Matrix-518 comes with a free GNU tool chain for users to develop C/C++ programs. Comprehensive examples are also available in Matrix-518 product CD to demonstrate how to access I/O interface and hardware features.

Matrix-518’s Linux environment is highly scalable and configurable. A variety of driver modules and software utilities is included on the product CD. Advanced customization service is also available upon request.
