SAN JOSE, Calif., Oct. 6 /PRNewswire/ -- Gumstix, Inc. today introduced a new expansion board for its tiny Overo(TM) computer-on-module (COM) series - the Chestnut43. The Chestnut43 is the first installment of Overo expansion boards that both connect via 10/100 baseT Ethernet and support an LCD screen. Design engineers who are building network management, time and attendance, security, kiosk or other information management devices can incorporate a Chestnut43 expansion board with any Gumstix Overo COM into their product design.

The Chestnut43 expansion board connects directly to a 4.3" Samsung LCD display with touch screen @ 16 bpp through a 45-pin FPC connector. It also features support for 10/100baseT Ethernet, EHCI (USB 2.0 high-speed) Host, USB client, USB console, audio in and audio out. A connected 5v wall adapter powers both the Chestnut43 and the attached Overo COM. Gumstix markets US, UK and EU versions of wall adapters for their customers located worldwide. A 40-pin unpopulated standard header presents signals for PWM, I2C, SPI, A/D, processor control, GPIO and analog.

"Customers building network-attached products that manage data or graphical information to an LCD display can now design their new product using our modular, OMAP(TM) processor-based Overo product line," said W. Gordon Kruberg, President and CEO of Gumstix. "The Chestnut43 expansion board works with each and every Overo computer-on-module making the production of a wide variety of Ethernet-attached products with a 4.3" LCD screen quicker and easier than before."
