Dec 5, 2007 — by Jonathan Angel — from the LinuxDevices Archive — 3 views

VersaLogic is shipping a new extended-temperature version of its EBX format single-board computer (SBC) based on a Geode LX-800 processor. The “Python” SBC supports reliable fanless operation, and can now operate in environments from -40 to 85 deg. C, according to the company.

First announced in April, the Python is based on an AMD Geode LX-800 processor (which dissipates less than 12W) along with an AMD Geode CS5536 companion chip. The board supports up to 1GB of DDR RAM, and features a field-upgradeable BIOS. I/O includes four USB 2.0 ports, dual 10/100 Mbps Ethernet channels, four serial ports (two RS-232, two RS-422/485), analog- and digital-output graphics, AC97 stereo sound, and a CompactFlash socket.

Other features, according to the company, include:

  • ATA-5, UDMA66 IDE interface
  • LPT parallel port supporting EPP, ECP, and SPP
  • 32 lines of TTL-level digital I/O
  • 8-channel, 12-bit analog input port
  • Three PMW outputs and tachometer inputs
  • Keyboard and mouse ports

As per the EBX specification, the Python has a PC/104-Plus expansion site, which accepts a stack of PC/104 and/or PC/104-Plus modules. In addition, however, it also contains VersaLogic's proprietary SPX expansion interface, which the company touts as “an inexpensive solution for additional I/O including analog, digital, CANbus, relay switching, and more.”

The EBX SBC is compatible with Windows CE, Windows XP Embedded, QNX, VxWorks, and Linux, the company said.

The extended-temperature version of the Python is available from stock. Pricing is $20 more than the standard version, at approximately $650 in production quantities.
