Arcom is shipping a new “ultra-low power” XScale-based EPIC format single-board computer (SBC). The Zeus SBC supports Linux, and takes advantage of the power saving modes of the PXA270 processor. It targets asset monitoring, vehicle tracking, and mobile information displays, according to the company.
