Applied Data Systems (ADS) will soon ship an upgraded version of its compact XScale SBC based on an Intel PXA270 processor. The BitsyXb, which supports embedded Linux, incorporates five power management modes that minimize power consumption in handheld, wearable, and unmanned applications, according to the company.
