with proven success in a wide range of vertical markets.
The BitsyXb,
based on the Marvell PXA270, offers a rich set of graphics, communications,
and I/O capabilities. The BitsyXb can be used as a stand-alone single board
computer or can be integrated with a standard or custom adapter board for
further feature expansions, including Power over Ethernet. The Bitsy Xb is
designed as low-cost, application-ready platform that can reduce the product-
to-market cycle from years to several months. To date, the Bitsy family
of embedded computers from Eurotech Inc. has been quickly and readily
“reconfigured” to satisfy dozens of application requirements.
Eurotech’s quick-turn capabilities are based on a world class engineering
house with expertise in quickly and successfully reconfiguring systems using
a deep reserve of hardware and software device technologies.
