EM-X270
is a full-featured computer board, designed specifically for handheld /
mobile implementations. Its functional contents are similar to the latest
generation of Pocket PC's and smartphones, including all types of
wireless, satellite and cellular connectivity found in today's
state-off-the-art mobile devices. Yet, it is designed to serve custom
implementations, retaining the flexibility expected from an embedded
computer board. Available with an optional display, battery with
charger
and keypad, the EM-X270 offers a self-contained solution requiring just
an enclosure for implementing the final custom product. The feature set of the
EM-X270 board combines a
32-bit CPU, SDRAM, Flash Disk and vital computing peripherals. On-board
wireless interfaces include WiFi, Bluetooth, GPS and cellular
Voice/GPRS modem. The last interface enables the device to act
essentially as a customized cellular phone.
EM-X270 has several connectors and
slots as used in PDA's and also an internal extension connector for
application-specific add-on's. Ready-to-run Windows CE and Linux
packages are available from CompuLab.
