PC/104-Plus SBC uses eight Watts

Sep 10, 2008 — by Jonathan Angel — from the LinuxDevices Archive

VersaLogic has modified one of its long-running single-board computers (SBCs) to operate fanlessly, using just eight Watts of power. The PC-104/Plus-based Cheetah EPM-32v runs Linux, targeting low-power embedded applications in medicine, avionics, or security, says the company.

VersaLogic's Cheetah, first introduced in April 2006 with a 1.6GHz Pentium M processor, is a two-module PC/104-Plus boardset. Its separate 3.8 x 3.6 inch processor and I/O boards provide two serial ports, two USB 2.0 ports, Ethernet, IDE, a parallel port, audio, and PS/2 keyboard/mouse support. The Cheetah also features support for both analog monitors and LVDS flat-panels, according to the company.

Earlier this year, VersaLogic revamped the Cheetah to comply with the European Union's RoHS directive, adopting lead-free solder, reformulated plastics, and other changes. The modified board, seen below left, was readily identifiable by its switch to a red circuit board. While the revised, 1.6GHz Cheetah had no functional changes from the 2006 original, it also became available in both standard- (0 to 60 deg. C) or extended-temperature (-40 to 85 deg. C) versions.

Now, the Cheetah has been tweaked again in a new EPM-32v variant, which adopts a 1.0GHz ULV (ultra low voltage) Celeron M processor. As a new photo (above right) shows, the device can now do without a fan, and it uses just eight Watts of power, claims VersaLogic.

As before, the SBC includes a CompactFlash socket, plus a PC/104-Plus interface that supports both ISA and PCI add-on modules. Standard pass-through connectors allow the board to be used above other PC/104 modules, the company adds.
