Notes: *In-rush measured with video, 128MB DDR PC2700 RAM memory, and power connected.
**The BIT (burn in test) current was measured using with 128MB DDR PC2700 RAM, video,
Ampro I/O Interface board, floppy (1), IDE HDD (1), PS/2 keyboard & mouse, 4 Serial loopbacks,
externally powered USB CD-ROM (1), externally powered USB HDD (1), USB Jump-Drive (1),
USB CompactFlash reader with 64MB CompactFlash card (1), onboard 64MB CompactFlash card, and
two operating Ethernet channels. LittleBoard 800 used Windows 2000 as OS.

Thermal/Cooling Requirements

The CPU, Memory Hub, I/O Hub, and voltage regulators are the sources of heat on the board.
The LittleBoard 800 is designed to operate at the maximum speed of the respective CPUs,
600MHz, 1.0GHz, or 1.4GHz. The Celeron M CPUs require a heatsink but no fan for –
40°to+85°C operation. The Pentium M CPU requires a heatsink but no fan for +0°to+70°C
operation, but does require a fan above +70°C (+70°C to+85°C operation).
