Rev. 1N02G and older of Vybrid have a serios bug in battery voltage driven parts. We do not
recommend to use a battery for this parts. Freescale will release a new revision
power consumption (Linux desktop idle, only power connected)
300mA
maximum power consumption 5V (summary all chips):
1000mA
Power consumption of connected devices like display, USB devices, SD card has to be add-
ed !

Shield to GND connection
There is the possibility to add a shield ground to signal ground connection on both mounting
holes on front side. There are 0603 shapes on the solder side of the board to add a connec-
tion. This gives customers the possibility to change EMV characteristic. On default this parts
are not mounted and the shield ground is not connected to the signal ground.
