The OnRISC Alena is an ARM9-based RISC industrial embedded computer. The great variety of interfaces like LAN, CF, USB, I²C, serial interface, CAN interface, digital I/O makes it easy to connect various industrial devices to the OnRISC. Because of CAN and RS485 options the Alena is good in monitoring field bus systems.

Compact dimensions and DIN Rail mounting capability make the OnRISC to a space saving and flexible mounting industrial computer. It is feasible to be installed even in space limited environments. The internal microSD slot protects the system software against accidentally removal.

Due to RISC based architecture the OnRISC has very small power consumption, so fanless heat dissipation is possible. Working in a wide temperature range from -10°C up to 65°C the OnRISC can be applied in under harsh industrial conditions. Therefore the OnRISC is downright designed for industrial automation.

The embedded computer runs full-featured Debian GNU/Linux on ARM operating system Kernel 2.6. With Debian's repository database it is easy to install and update the free software on the OnRISC. The OnRISC is capable to act directly as software development host, WEB, Mail, Print and Database server or as a desktop computer with X11 window manager and many more.

  BuildRoot
BuildRoot is a set of Makefiles and patches that allows to easily generate a cross-compilation toolchain, a root filesystem and a Linux kernel image for the target. Buildroot can be used for one or more of these options, independently. The benefits are :
  • No need to supply the toolchain, will be built automatically
  • Choice between various file systems for the target image
  • Builds a very small and quick booting system that suits the needs
  • Drivers compiled as modules will be automatically installed on the file system image
  • many more …
