5.2 GPIO BUS Connectors
The V2-EVAL board features a set of 6 connectors providing access to GPIO capable pins on the VNC2
device. The GPIO pins are distributed across 6 connectors. The configuration of each connector is
outlined in subsequent sections. Further each connector has a 5V and 3.3V power and GND pins.

Notes:
(3)
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.
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.
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.
