5V power rail.
Notes:
(29) All VNC2‟s IO pins can be driven from 3.3V LVTTL TTL logic levels.
The use of these pins for GPIO is set by the IOMUX on the VNC2 device. The pins are shared
by other connectors on the board. Care should be taken to ensure that pins are not driven
from other headers on the board.
(30) This pin is connected to 3.3V regulator output. External device can draw no more than 100mA
when board is powered from an external power supply and no more than 50mA when the
board is powered from USB bus.
(31) This pin is connected to the board‟s 5V power rail. External device can draw no more than
250mA when board is powered from an external power supply and no more than 50mA when
the board is powered from USB bus.
