armStone, Single Board Computer in PicoITX form factor
For solutions with Computer on Module (COM), which need a base board, a Single Board Computer (SBC) in an established form factor offers an alternative. The development of a base board is therefore unnecessary here, so costs are reduced and development time is shortened significantly (Time-To-Market). armStone offers all common interfaces (via standard bushes or multi-pin connector). A display can easily be connected via a LVDS interface. Also, a further display/ screen interface via (e.g.) DVI is available. The PicoITX form factor is perfectly constructed for small, but powerful applications. With a size of 100 x 72 mm, this PicoITX form factor is suitable for compact devices, as well as for portable ones. All standard bushes are lead through the long side and therefore can be placed at the back of the body. armStone has a Single Supply of 5V. Depending on the CPU, the power consumption can only be a few Watt, making it possible to run the armStone without fan or cooling element.
What use has the best hardware without software ?
For this reason, the armStone is always shipped with a pre-installed operating system. At present, WCE 6.0/ R3, WEC 7 (including Microsoft license) and Linux are available, Android and probably other OS will follow. Certainly you have the possibility to install other existing kernel versions via WCE 6.0 R3/ WEC 7, or to create own kernels. Via Linux, a BSP and the Toolchain are available (Buildroot).
