Linux ARM9 Box, 2x Ethernet, 4x RS232/422/485, 2x USB Host US$370.00

Linux ARM9 Box, 2x Ethernet, 4x RS232/422/485, 2x USB Host

The Matrix-512 is a mini-mighty Linux-ready ARM9-based computing platform for embedded headless run-only application. It comes equipped with two Ethernet, four RS-232/422/485 TTY ports, two USB host ports, plus one internal SD memory card slot and 21 CMOS/TTL-level GPIOs in a small package measuring only 160 104 32 mm.

100% Linux Compatible; Hassle Free

The Matrix-512 is a true Linux computing platform and it supports versatile file systems. You can operate the Matrix-512 the same way as you do a normal Linux desktop.

Support Wire and Wireless Networking

The Matrix-512 comes with two standard 10/100Mbps Ethernet ports for wired networking. In addition, it is easy to add IEEE-802.11b/g WiFi support by simply plugging an USB WiFi dongle into the Matrix-512.

Four 921.6Kbps TTY Ports

Also, the Matrix-512 provides four 921.6Kbps RS-232/422 /485 TTY ports. Port 2 features full RS-232 supporting for modem connection. Port 1, Port 3 and Port 4 support standard RS-232.

Twenty-one TTL-level GPIOs

The Matrix-512 comes with 21 CMOS/TTL-level digital I/Os. Each pin can be programmed individually as input or output.

Optional 2GB SD Card for Data Storage

Users can install one standard SD Flash memory card, up to 2GB, into the Matrix-512 as an additional hard drive.

GNU Tool Chain for Application Development

Open-source GNU Tool Chain, including C/C++ cross-compiler and POSIX standard C/C++ library, is bundled with the Matrix-512 for free.

Note: The Matrix-512 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 listed in the options. To use the adapter, you'll just need to supply two wires between the adapter and the Matrix-512.
