Electrum 100


The Electrum 100 is a single board computer designed for control applications that require high performance, networking and reliable multitasking capabilities. Powered by an Atmel AT91SAM9G20 ARM926EJ-S core at 400 MHz, it can fulfill the most demanding requirements in monitoring, instrumentation, data acquisition, process control, factory automation and many other applications.

An I/O Plus option is available that includes an eight channel 12-bit ADC, a four channel 12-bit DAC and their header connectors. This option is recommended for applications using sensors or actuators with analog interfaces.

Base Electrum 100



Debian Linux on the Electrum 100 provides a stable and reliable operating system base that can be easily extended using readily available libraries and applications. Linux is loaded from NAND Flash, simplifying software development and distribution. Secure remote access can be implemented via web or command line interfaces, providing off-site monitoring and maintenance capabilities. Many popular Linux applications are available or can be easily ported using the GNU compiler collection as well as popular IDEs including Eclipse and Code::Blocks. x86 Linux is the recommended development environment with ARM cross compilers and other development tools readily available. If you are restricted to using a Windows PC for development, you may consider VMWare or other virtualization software that allows you to run Linux from Windows.

Ports of popular Basic, LUA and Python development tools are available for the Electrum 100 to reduce application development time and simplify integration with code libraries developed for industrial and scientific environments. Using these tools, you can achieve significant functionality in a very short time. These open source tools can be easily extended, allowing a virtually unlimited number of possibilities.
