Power Consumption
QuadMo747-x2000 module, like all Qseven
®
modules, needs a carrier board for its normal working. All connections with the external world come through this
carrier board, which provide also the required voltage to the board, deriving it from its power supply source.
Anyway, power consumption has been measured on +5V_S power rail that supplies the board. For this reason, the values indicated in the table below are real
power consumptions of the board, and are independent from those of the peripherals connected to the Carrier Board.
Power consumption in Suspend and Soft-Off States have been measured on +5V_A power rail. RTC power consumption has been measured on carrier board
’
s
backup battery when the system is not powered.
The current consumptions, written in the table of this page, have been measured using the following setup:
O.S. Windows 7 ultimate SP1
2GB DDR3
16GB SSD soldered onboard
Bios Release 1.04
USB mouse and keyboard connected
VGA display connected.
Network cable connected (except for Soft Off configuration)
