Electrostatic Sensitive Device
All COM 830 variants are electrostatic sensitive devices. Do not handle the COM 830, or processor, except at an
Supply Voltage Standard Power
12V DC ± 5%
Electrical Characteristics
Power supply pins on the module's connectors limit the amount of input power. The following table provides an overview of the limitations for pinout Type 2 (dual connector, 440 pins).

Power Consumption
The power consumption values listed in this document were measured under a controlled environment. The hardware used includes a COM 830 module, Ampro baseboard, CRT monitor, SATA drive, and USB keyboard. The complete testing environment was powered by a Direct Current (DC) power supply that is set to output 12V. The current consumption value displayed by the DC power supply's readout is the value that is recorded as the power consumption measurement. All recorded values are approximate.
The power consumption of the Ampro baseboard (without module attached) was first measured and the resulting value was later subtracted from the overall power consumption value measured when the module and all peripherals were connected.
The SATA drive was powered externally by an ATX power supply so that it does not influence the power consumption value that is measured for the module. The USB keyboard was detached once the module was configured within the OS.
Each module was measured while running Windows XP Professional with SP2 (service pack 2) and the “Power Scheme” was set to “Portable/Laptop”. This setting ensures that Core 2 Duo and Core Duo processors run in LFM (lowest frequency mode) with minimal core voltage during desktop idle. Celeron M processors do not support this feature and therefore always run at the same core voltage even during desktop idle. Each module was tested while using a swissbit® DDR2
Windows XP Professional SP2
Desktop Idle (1000MHz for 667MHz FSB or 800MHz for 533MHz FSB modules) 100% CPU workload (see note below)
