AT91SAM9G20 Linux Box: 8x Isolated RS485, 2x LAN, 2x USB US$660.00

AT91SAM9G20 Linux Box: 8x Isolated RS485, 2x LAN, 2x USB

AT91SAM9G20 Industrial Linux Box Computer

  • Atmel 400MHz ARM9 processor (AT91SAM9G20)
  • Linux kernel 2.6.29 with file system
  • 64MB SDRAM, 128MB NAND Flash, 2MB Data Flash
  • microSD socket inside the box; supports up to 32GB
  • Failover mechanism against system crash
  • Two 10/100M Ethernet ports
  • Eight isolated RS485 serial ports, 2500Vrms isolation
  • Two USB hosts, USB2.0 compliant
  • 21 GPIOs in DB25 connector
  • Less than 3W power consumption
  • Power input 9-48V DC
  • GNU C/C++ tool chain for Linux and Windows

Artila's Matrix-516 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-516 ensures high system performance. Matrix-516 is equipped with multiple I/O interfaces, including two LANs, eight isolated RS485 serial ports, two USB hosts, one microSD, 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-516.

Matrix-516 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 systems, scenario control systems, and factory automation.

Matrix-516 also provides a useful fail-proof design for system backup and recovery. Normally, Matrix-516 boots up from its NAND Flash. However, the Data Flash in the Matrix-516 includes a backup Linux file system as well, which will boot up Matrix-516 automatically in case the primary NAND Flash fails. If the Matrix-516 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-516s.

With pre-installed Linux OS, you can easily operate Matrix-516 via Telnet, or transfer files using FTP. Matrix-516 comes with a free GNU tool chain for you to develop C/C++ programs. Comprehensive examples are also available on the Matrix-516 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.

Note: The Matrix-516 has a screw terminal power connector. The power supplies offered below as an add-on option do not directly connect. If you don't want to cut off the supply's barrel connector, there is a barrel jack adapter also listed in the options. To use the adapter, you'll just need to supply two wires between the adapter and the Matrix-516.
