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.
The following pins are only accessible on VNC2 when the onboard multiplexer select input is high. See
section 6.4 for details.
This pin is connected to 3.3V regulator output. External device can draw no more than 100mA when board
is powered from power supply and no more than 50mA when the board is powered from USB power bus.
This pin is connected to the board‟s 5V power rail. External device can draw no more than 250mA when
board is powered from power supply and no more than 50mA when the board is powered from USB power
bus.
